US and China ambassadors identify areas of cooperation as well as danger zones

US and Chinese envoys commemorated the 45th anniversary of official diplomatic ties on Tuesday by mixing warm sentiments about last year's summit between their leaders with warnings about Taiwan and trade restrictions that suggested the two sides are far from understanding each other's intentions.

Washington's ambassador to Beijing, Nicholas Burns, addressed an audience at the Carter Centre in Atlanta via video, praised the Chinese government for "concrete action" to block the flow of fentanyl precursors from the US and restarting military-to-military dialogue while underscoring Washington's hard line on sales of advanced technology to China.

His comments came hours before the Pentagon announced the resumption of high-level military-to-military discussions - the US-PRC Defence Policy Coordination Talks - which were halted when bilateral tensions boiled over in 2022. Restarting the talks was one of the pledges made during the summit in November in California.

"We've seen action, real action, concrete action by the government in Beijing to begin to shut off the flow of precursor chemicals, to take action against those Chinese companies that were involved," Burns said, before turning to the need for technology export restrictions.

"We simply are not going to allow the People's Liberation Army to acquire our most sensitive technology so that it can compete with us militarily, and there'll be no compromise on those advanced semiconductors, and other technology restrictions that we've put into place," he added.

A string of moves by US President Joe Biden's administration to restrict the provision of advanced US technology to China has been a bilateral sore point; Beijing contends the actions amount to an effort to undercut the competitiveness of Chinese companies.

In August, Biden announced new restrictions on investments that American companies could make in China in the areas of "semiconductors and micro electronics, quantum information technologies and certain artificial intelligence systems".
