But the White House was quick to say at the time that the discussions would not resemble formal arms reduction talks, like those the US has had with Russia.
Since then, US officials had expressed frustration that China showed little interest in discussing steps to reduce nuclear weapons risks.
China has more than 500 operational nuclear warheads in its arsenal and will probably have over 1,000 warheads by 2030, the Pentagon said in October. But Beijing has long argued that the US already has a much larger arsenal.
The arms talks would occur before a likely meeting between US President Joe Biden and Chinese President Xi Jinping in San Francisco in November, although a senior Biden administration official said on Tuesday important details have yet to be hammered out.
A flurry of China-US diplomatic engagements in recent months, largely at Washington’s request, has sought to salvage what were rapidly deteriorating ties between the two countries following the US downing in February of a suspected Chinese spy balloon over the United States.
Daryl Kimball, executive director of the Washington-based Arms Control Association, said the overdue arms talks would likely focus on promoting greater transparency of each countries’ nuclear doctrines and more effective crisis-communication channels.
“I don’t think, however, we should expect breakthroughs in the near term. That’s going to take time and give and take from both sides,” Kimball said.
