TikTok: ByteDance accused of helping China spy on Hong Kong activists

TikTok’s owner ByteDance has been accused of allowing Chinese Communist Party (CCP) members to access the data of Hong Kong civil rights activists and protesters.

Users who uploaded “protest-related content” were also identified and monitored, former ByteDance executive Yintao Yu alleges in a US court filing.

The CCP members were also able to access US TikTok user data, Mr Yu says.

A ByteDance spokesperson denied the claims, describing them as “baseless”.

The allegations are contained in a San Francisco Superior Court filing made this week as part of a lawsuit brought by Mr Yu.

In the filing, Mr Yu claimed that members of a CCP committee had access to a “superuser” credential, which was also known as “god user”, which allowed them to view all data collected by ByteDance.

He also alleged that the committee members were not ByteDance employees but were physically present at the company’s offices in Beijing.

This was common knowledge among senior executives, said Mr Yu, who for around a year from August 2017 was a head of engineering in the US for ByteDance.

The filing also alleged that in 2018 the CCP committee members used their “god credential” to “identify and locate the Hong Kong protesters, civil rights activists, and supporters of the protests”.

Hong Kong saw huge protests in 2014 – the so-called Umbrella movement – where people demanded the right to elect their own leader. After that, there were smaller demonstrations by civil rights activists. Much of this visible dissent has disappeared since Beijing cracked down with a draconian national security law after the anti-government 2019 protests.

When contacted by the BBC, a ByteDance spokesperson strongly denied the allegations: “We plan to vigorously oppose what we believe are baseless claims and allegations in this complaint.”

They also said that Mr Yu was employed by the company for less than a year and in that time worked worked on a now-discontinued app called Flipagram.

“It’s curious that Mr Yu has never raised these allegations in the five years since his employment for Flipagram was terminated in July 2018. His actions are clearly intended to garner media attention,” the ByteDance spokesperson added.

Mr Yu’s claims come as TikTok is under intense scrutiny around the world.

In March, TikTok’s chief executive Shou Zi Chew faced four-and-a-half hours of questioning at a US congressional hearing.

Mr Chew was quizzed by both Democrats and Republicans over the app’s data security and privacy practices, and its alleged ties to Beijing.

A spokesperson for TikTok said afterwards that the politicians were “grandstanding”.

In May, Montana became the first US state to pass a sweeping ban on the Chinese-owned video-sharing platform.

The ban is due to take effect in January 2024. It will make it illegal for app stores to offer TikTok, but does not ban people who already have TikTok from using it.

TikTok has sued to block Montana from imposing the ban, saying it conflicts with US free speech rights. Montana, which has a population of just over one million, banned the app on government devices last December.

TikTok says it has 150m American users. Although the app’s user base has expanded in recent years, it is still most popular with teenagers and users in their 20s.

Polish tourists fled to safety as a double-decker bus taking them to Ayutthaya burst into flames and was destroyed on an expressway in Bangkok’s Chatuchak district on Wednesday morning.

The white and red tour bus was carrying 15 tourists from Poland and their Thai guide. There were no injuries reported, but many passengers lost their luggage to the fire.

The bus burst into flames while outbound on the Si Rat Expressway, above the central bus terminal near the exit to Kamphaeng Phet 2 Road, about 7.55am, according to traffic radio FM91 Trafficpro.

Fire trucks and crews and an expressway rescue team were rushed to the scene. They took about 20 minutes to put out the fire. By then the bus was totally gutted.

The fire caused heavy traffic congestion in the area.

The bus driver, Khuanchit Kaewmanee, 46,  said he had picked up the 15 tourists and their guide at the Bangkok Palace Hotel in Makkasan area of Ratchathewi district. They were going to Ayutthaya province.

A short time later, while outbound on the expressway, he saw smoke coming from a luggage compartment, and there was the smell of something burning.

He immediately parked the bus on the left side of the expressway and got out to check. All passengers were asked to also leave the vehicle.

Mr Khuanchit said he managed to remove some passengers’ bags from the bus before it burst into flames and he was forced to retreat.

The bus was totally destroyed. Police were investigating the cause of the fire.

Open-standard, open-source tech body defies US sanctions

The launch of a new RISC-V software association makes open-standard integrated circuit design and open-source software even more of a challenge for the US government’s efforts to stop the development of Chinese high-tech and bend Europe to its geopolitical will.

On May 31, Linux Foundation Europe announced the RISC-V Software Ecosystem (RISE), which it described as,

a new collaborative effort that brings together global industry leaders committed to accelerating the availability of software for high-performance and power-efficient RISC-V cores [processing units] running high-level operating systems for a variety of market segments.

Those market segments include cloud computing, data centers, automobiles, mobile phones and other consumer electronics. Hosted by Linux Foundation Europe, RISE supports the global open standard activities of RISC-V International.

Gabriele Columbro, General Manager of Linux Foundation Europe, notes that,

The RISE Project is dedicated to enabling RISC-V in open-source tools and libraries (LLVM and GCC, etc) to speed implementation and time to market. RISC-V is a cornerstone of the European technology and industrial landscape so we’re honored to provide a neutral, trusted home for the RISE Project under Linux Foundation Europe.

Thirteen companies from the US, Europe, Japan, South Korea, Taiwan and mainland China form the RISE Governing Board: NVIDIA, Qualcomm, MediaTek, Intel, Samsung, Google, Andes, Red Hat, Imagination Technologies, Rivos, SiFive, Ventana and T-Head.

It’s significant that T-Head is included. It is a wholly-owned subsidiary of Alibaba, a fabless semiconductor design company that develops application-specific ICs for artificial intelligence, cloud computing, industrial, financial, consumer electronics and other applications. In effect, it is the Alibaba group’s semiconductor division.

According to T-Head Vice President Jianyi Meng,

T-Head has been contributing to the software ecosystem through initiatives such as putting various operating systems onto RISC-V and contributing an integrated development environment to the RISC-V community. Together with other global business leaders for the RISE Project and our partners across sectors, we can further drive the growth of the open-source software ecosystem.

Speaking at a conference in Shanghai at the beginning of March, Meng said,

The development of RISC-V requires global innovation collaboration, from chips to software, applications and terminals. T-Head is pulling together the major ecosystems so that global developers and partners can better use and develop RISC-V technologies.

At that time, T-Head and Alipay also announced plans to enable secure payments on wearable devices using embedded RISC-V processors.

The rise of RISC-V, particularly in China, is likely to be negative for Arm and its Japanese owner Softbank, which plans to take Arm public later this year. Proprietary instruction-set architectures from Arm are seen as high-risk by the Chinese due to potential US influence on their owner.

RISC-V is an open standard instruction set architecture based on reduced instruction set computer design principles. It was conceived at the University of California, Berkeley, in 2010.

The RISC-V Foundation was established in Delaware in 2015 to support and manage open-source technology, with the Institute of Computing Technologies of the Chinese Academy of Sciences as one of the founders.

Other founding members include Google, Qualcomm, Western Digital, Hitachi and Samsung. Other Chinese members include Huawei, ZTE, Tencent and Alibaba Cloud. Altogether, the association has more than 300 corporate, academic and other institutional members around the world

Foundation fled the US

In 2020, the Foundation was incorporated in Switzerland as the RISC-V International Association, moving out of the United States to avoid potential disruption caused by then-president Donald Trump’s anti-China trade policy. For more information about this, see Open-source IC architecture taking off in China.

The GCC (GNU Compiler Collection) mentioned by Gabriele Columbro is part of the GNU Project, a collaborative effort for the development of free software founded in 1978 by Richard Stallman at MIT.

Linux, the open software kernel created by the Swedish-Finnish software engineer Linus Torvalds in the early 1990s, is normally used with the GNU operating system.

GCC consists of free software programs from the GNU Project and other parties, created in an open environment in order to “attract a larger team of developers, to ensure that GCC and the GNU system work on multiple architectures and diverse environments.” GCC is one of the world’s largest free software programs.

GNU defines itself as “an operating system that is free software – that is, it respects users’ freedom.” Its “four essential freedoms” are,

  • The freedom to run the program as you wish, for any purpose.
  • The freedom to study how the program works, and change it so it does your computing as you wish. Access to the source code is a precondition for this.
  • The freedom to redistribute copies so you can help others.
  • The freedom to distribute copies of your modified versions to others, By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Freedom to distribute “means you are free to redistribute copies, either with or without modifications, either gratis or charging a fee for distribution, to anyone anywhere.”  

The explanation goes on to note that:

Sometimes government export control regulations and trade sanctions can constrain your freedom to distribute copies of programs internationally. Software developers do not have the power to eliminate or override these restrictions, but what they can and must do is refuse to impose them as conditions of use of the program. In this way, the restrictions will not affect activities and people outside the jurisdictions of these governments. Thus, free software licenses must not require obedience to any nontrivial export regulations as a condition of exercising any of the essential freedoms.

According to the Linux Foundation, open-source technologies that are published and made publicly available are not subject to the Export Administration Regulations of the Bureau of Industry and Security of the US Department of Commerce.

China has involved itself in RISC-V from the beginning and that – particularly in view of the Biden administration’s liberal and expanding use of sanctions – has turned out to be a very good idea.

US to support ‘effective, stable, democratic govt’ in Thailand

WASHINGTON: Thailand is in a “delicate phase” after the May 14 election and the goal of the United States is to support an “effective, stable, democratic government” there, a top US official for the Indo-Pacific region said on Tuesday.

“We’ve watched carefully the election,” White House Indo-Pacific Coordinator Kurt Campbell told the Hudson Institute think tank. “This is a delicate phase in terms of the formation of a government.”

The opposition Move Forward and Pheu Thai parties dominated in last month’s election in Thailand, dealing a resounding defeat of conservative parties backed by a military that has controlled government since Thailand’s last coup on May 22, 2014, which ousted the Pheu Thai-led administration.

They have been seeking to form a coalition government with six other parties. However, Move Forward leader and prime ministerial front-runner Pita Limjaroenrat faces an uphill battle to woo members of an unelected, conservative-leaning Senate to back him in a legislative vote on a prime minister expected by August.

On Tuesday, Mr Pita played down an effort to disqualify him over a stock ownership issue, insisting he violated no rules and that rivals were determined to keep him from the top job.

The US is seeking to boost ties with allies and partners throughout Asia at it pushes back against China’s expanding power, and Campbell said Washington wanted to sustain a strong bilateral relationship with Thailand, its oldest treaty ally in the region.

“Many companies are invested there; we have strong military programs and engagements with the Thai armed forces,” the US official said.

“I think it is undeniable that the politics of Thailand have been unstable and complicated,” he said, adding: “I think our goal would be to support an effective, stable, democratic government in Thailand and then work consequentially with it.”

Biden’s contrasting styles and priorities

For weeks, US President Joe Biden publicly demanded that the issue of raising the debt ceiling was a done deal and not negotiable. As the prospects of national default loomed, the Biden White House quietly began negotiations with Republican House Speaker Kevin McCarthy, and arrived at a compromise in the nick of time so as to avert default.

It seems Biden understood, after all, that avoiding the disaster of a default and the mortal pain on the American economy was more important than sticking by his guns. However, he apparently does not understand that the outcome of his negotiations with China is equally crucial to America’s future; his approach has been steadily unyielding, unfriendly and unhelpful.

Biden’s China team has adopted a strategy of saying one thing and then doing just the opposite. Every one of his cabinet officers would declare that he or she wishes to meet with their Chinese counterparts to discuss cooperation and collaboration – but always on the US terms, meaning that the US reserves the right to discuss the issues it wants to discuss, but will continue to criticize, attack and sanction China on others.

This is the way an imperious hegemonic power acts toward a subordinate country and expects obeisance and compliance. Except China no longer sees itself as a lesser power to the US. China has simply ignored the many White House requests. 

The latest example came at the Shangri-La security forum in Singapore. The US had asked for a meeting between Defense Secretary Lloyd Austin and his counterpart Li Shangfu on the sidelines of the forum. China refused. The US promptly accused China of irresponsible behavior endangering the bilateral relations by not keeping the lines of communication open.

US wants to meet with China for what purpose?

Of course, communicating and agreeing to face-to-face meetings are two separate matters. China expects prospects of a useful outcome to justify arranging in-person meetings. For possible constructive results, China wants to see serious and sincere gestures from the US.

All too frequently in previous meetings, the American officials viewed them as opportunities to crow about China giving in to American demands, whether actually true or not.

That Biden did not even bother to lift the personal sanction imposed on Li Shangfu during Donald Trump’s administration and still expects to have a summit meeting of military leaders seems stupid and arrogant.

Mind you, Li was sanctioned for purchasing fighter jets from Russia on behalf of China as part of his duty at the time in charge of procurement for the People’s Liberation Army (PLA). What right does the US have to sanction an official of another country for doing his job? India buys arms from Russia; Turkey buys arms from Russia, apparently with no sanctions. 

This is just one example of Secretary of State Antony Blinken’s “rules-based international order.” That order is arbitrary and is whatever the US says it is. Blinken was hankering for an invitation to meet in Beijing. Then the wandering weather balloon from China gave him the excuse to cancel the visit on an invitation that never came. Not only that, he reaped a PR dividend by blaming China for the debacle.

Examples of hypocrisy and deception abound. Biden warmly embraced Xi Jinping in Bali and swore by the one-China principle and that Taiwan is part of China. Then he openly sells arms to Taiwan and impose complete sanctions of export semiconductor technology to China. 

Treasury Secretary Janet Yellen goes out of her way to ask China for support of the US treasury debt and then goes to Africa to warn African nations to beware of China’s debt-trap diplomacy.

Commerce Secretary Gina Raimondo asked for a meeting with her counterpart to discuss increasing bilateral trade. What she actually meant was she wanted China to buy more but did absolutely nothing to reduce the tariffs imposed on Chinese imports by the Trump administration that might actually raise the volume of bilateral trade.

US on the path of self-destruction

Decoupling from China is not his intention, Biden claims, but then every action by his team is just the opposite. Every prospective bilateral outcome has to be on US terms, or else. What the Biden White House does not appreciate is that it has embarked on a path of self-destruction for America.

The damaging blowback from Biden’s China policy may not be as obvious as not raising the debt ceiling, but there is a strong element of cutting off Uncle Sam’s nose to spite his face that the leaders in Washington seem oblivious to. Just a few examples follow.

When Biden first came to office, if he had intended to resume a constructive relationship with China, he could have eliminated the tariffs levied by Trump on Chinese imports. Instead, he retained the tariffs despite hurting the American consumer much more severely than China’s manufacturers. The desire to inflict pain on China far outweighed protecting Americans from even greater pain.

Whether it’s assembling new subway cars with Chinese components, installing the world’s most cost-effective port-handling cranes, or surveillance cameras made in China, Washington let its paranoia run wild and turned away the cost savings from buying superior products from China.

The sanction of Huawei is an extreme case. Huawei has developed the world’s most advanced fifth-generation (5G) telecommunication system, which has received acceptance around the world. Because of US fear of being spied upon, Washington not only has refused to buy from Huawei but pressured many of its allies to rip out billions of dollars’ worth of Huawei equipment already installed. 

After enduring the US sanctions for three years, Huawei has just announced the complete replacement of operating software based on Western technology. It will now sell to the world without any constraints, while the United States’ allies suffer hundreds of billions of dollars from the teardown of already installed Huawei equipment and the huge opportunity costs 0f not having a state-of-the-art telecommunication system.

China has also surpassed the US in EVs

Of course, telecom is not the only technology where China has surpassed the US. Among others, China’s emergence as the world’s leading producer of electric vehicles and owner of leading technology for the batteries that go into the EVs has taken the West by surprise. China has become the No 1 exporter of EVs around the world. 

Ford and Tesla, among many automakers in the West, would like CATL to build an advanced battery plant next to their EV plants in the US. (CATL is abbreviation for Contemporary Amperex Technology Ltd headquartered in Ningde, China, and is an acknowledged leader in EV battery technology.) 

The potential deals raise interesting questions. Will Beijing forbid CATL’s transfer of battery technology to the US along the same logic as Washington’s semiconductor sanction on China? Or will some senator, such as a Marco Rubio, raise the specter of Chinese batteries in EVs forming a terrifying network for spying on America?

Biden thought he had cleverly jumpstarted the US semiconductor industry by snatching a leading-edge operation from Taiwan Semiconductor Manufacturing Co to Phoenix, Arizona. Now the TSMC management has discovered that they are not able to hire enough people from an American workforce that are qualified and/or willing to work in the rigors of a Taiwanese operation.

In the meantime, the people of Taiwan are feeling increasing betrayed by America’s ham-fisted ways. This is a classic lose-lose outcome in the making.

Another is Defense Secretary Austin’s insistence on playing the “freedom of navigation” game in waters around China and flying surveillance planes off coastal China. Since Nancy Pelosi’s visit to Taipei last year, China has emphasized its territorial claim over Taiwan and has been increasingly aggressive in responding to American intrusions in Beijing’s back yard.

Just last Saturday, a US destroyer along with a trailing Canadian frigate attempted to sail through the Taiwan Strait, which China regards as its territorial waters. In response to this provocation, a Chinese destroyer intercepted the American warship and forced it to change course.

Obviously, the PLA is increasingly willing for a showdown over whether China’s territorial waters can continue to be treated as America’s international waters. The firepower and technology of the PLA warships have surpassed the Americans’, and the Chinese appear confident and ready to put it to a test. 

If the US Navy should succeed in provoking the PLA into a firefight, it is certain that both parties would be losers.

China has more friends than US has allies

Geopolitically, the US continues to count on the Group of Seven and a handful of other countries to be its allies. Biden’s stipulation is to insist on strict compliance of his foreign policy even at the expense of each ally’s own national interest.

Consequently, France is becoming a doubting Thomas about the wisdom of going along with the US, South Korea is trying to wriggle out of not losing China’s sales, as is ASML of the Netherlands. Germany and Australia in their own ways are holding on to their trade relations with China. In sum, the American alliance is increasingly questioning the shakiness of US leadership.

Concurrent to American hectoring over its version of “rule-based” order, 19 countries have expressed interest in joining BRICS (Brazil, Russia, India, China and South Africa) purely for the economic advantages of being a body that requires no military allegiance.

Saudi Arabia along with other oil-producing countries becoming members of BRICS+ will change the global alignment. The body will be far more populous and economically powerful than the US-aligned G7+.

And, by the way, a top agenda item for the new BRICS is to discuss a plan to introduce a new currency to replace the need to settle trade accounts in US dollars. This move is in direct response to Biden weaponizing the dollar and denying dollar access to countries he doesn’t like, such as Russia.

The Regional Comprehensive Economic Partnership (RCEP) has just come into full force. Members of the partnership consist of the 10 ASEAN countries plus China, Japan, South Korea, Australia and New Zealand. They will enjoy booming, tariff-free trade among themselves. The US is on the outside looking in.

Since China initiated the Belt and Road Initiative 10 years ago, around 150 countries have become beneficiaries of projects and investments through BRI. At reasonable financing terms, China supplies their expertise to build infrastructure such as ports, railroad, highways, bridges, airports and many others to enhance the economic development of the recipient country.

By far, BRI has been China’s most effective tool for making friends around the world. 

The US? It stands impotently on the sidelines and watches with envy, and occasionally throws stones by calling these BRI projects debt traps.

Despite Washington’s mighty effort to suppress and obstruct China’s rise, China has become relatively impervious to American sanctions and restrictions. Just like Huawei, China’s semiconductor industry will find ways around the ban.

At the same time, China has become the foremost trading partner to virtually every country in the world. China’s economy remains strong and technological innovations will continue, hardly affected by actions from Washington.

The Biden administration has concentrated virtually all its efforts on keeping China from rising, to no avail. At the same time, the administration has not done anything concrete to lift the competitiveness of the American economy.

In a long line of mediocre leadership, Biden may prove the be the worst.

China’s JF-22 hypersonic wind tunnel blows by US

China’s self-developed JF-22 wind tunnel is ready for hypersonic tests after passing a final evaluation conducted on May 30.

Based in the mountainous Huairou district north of Beijing and reputedly the world’s fastest, the wind tunnel can simulate the environment in which a spacecraft re-enters the atmosphere, according to Chinese physicists quoted in media reports.

The National Natural Science Foundation of China, managed by the Ministry of Science and Technology, recently held a meeting at the Chinese Academy of Science’s Institute of Mechanics in Beijing, China Central TV reported on Monday.

During the meeting, scientists confirmed that the JF-22 detonation-driven high-enthalpy shock tunnel project’s performance indicators including effective test time, temperature, pressure and nozzle flow had achieved international standards.

“The goal of the JF-22 wind tunnel is to accelerate the development of a space-to-earth shuttle system,” said Jiang Zonglin, a researcher at the Institute of Mechanics and head of the wind tunnel project. “If successful, the facility can also help reduce the cost of launching satellites and spacecraft by 90%.”

The JF-22’s construction began in 2018 and was completed in August 2021, according to state media. The tunnel has a length of 167 meters and diameter of four meters with an air flow range of three to 10 kilometers per second.

That makes it the largest and fastest wind tunnel in the world, capable of simulating hypersonic flight conditions up to Mach 30, according to the Institute of Mechanics, the owner of the facility, the South China Morning Post reported.

CAS researcher Han Guilai said in a lecture in 2021 that the JF-22 has the capability to simulate hypersonic flight conditions up to Mach 30 and could sustain such a runtime for an average of 130 milliseconds. LENS II, believed to be the most advanced wind tunnel in the United States, can only reach Mach 7 with a runtime of 30 milliseconds.

Han said then the JF-22, together with China’s JF-12 wind tunnel, would put China “about 20 to 30 years ahead” of the West. The JF-12 passed an acceptance check in May 2012 and can simulate flights of up to Mach 7.

Hypersonic competition

However, Chris Combs, an expert in hypersonic and aeronautical engineering, told EurAsian Times that China’s JF-22 claim ignores the “presence of a wide variety of decades-old facilities around the world.” He said several wind tunnel facilities around the world had already achieved speeds of Mach 20 and above.

Combs said Mach 30 speeds are only seen “during extraterrestrial return (Moon, Mars, etc.)”, meaning that “until they start launching missiles from the Moon, this isn’t even really military.”

He also pointed to problems with detonation-driven shock tunnels, stating that they “alter the air chemistry to the point that the aero will no longer be representative of flight.”

During the 1960s and 1970s, all NASA space shuttles and space launch systems were tested in the California-based Unitary Plan Wind Tunnel at the NASA Ames Research Center. The tunnel could only reach Mach 2 to 3.5. More tests were conducted by digital simulation with computational fluid dynamics (CFD) software.

Due to a lack of hypersonic wind tunnels, the US Department of Defense’s Defense Innovation Unit has reportedly considered skipping wind tunnel tests and instead getting data directly from actual flight testing.

An unnamed DIU spokesperson told Breakingdefense.com last September that the DIU is seeking commercial partners to demonstrate a test aircraft prototype that can fly and maneuver at greater than Mach 5, the minimum speed of hypersonic planes and weapons.

“I was surprised to know that the DoD wants to skip the wind tunnel tests and directly launch its hypersonic planes,” a Zhejiang-based columnist wrote in an article last September. “Such a practice violates the general procedures of scientific research.”

He said only wind tunnels, not software, can simulate actual hypersonic environments. He added that a wind tunnel with Mach 33 capability is useful as space shuttles will eventually re-enter the atmosphere at the “escape velocity” of 11.2 kilometers per second without deceleration.

However, a popular IT vlogger known as GeekLead said in a June 2020 video that China chooses to invest in wind tunnels because it lacks its own CFD software. He said senior Chinese officials usually favor investments in hardware over software as they prefer to see tangible results.

Other commentators claimed the US uses digital simulation of hypersonic tests but to date they haven’t worked as well as old-fashioned wind tunnels.
