During a summit, Chinese leader Xi Jinping urged US President Joe Biden to stop selling arms to Taiwan, but agreed to resume high-level military-to-military talks, Beijing said Thursday.

“The US side should... stop arming Taiwan, and support China’s peaceful reunification,” Xi told Biden, according to a readout from China’s foreign ministry.

“China will realize reunification, and this is unstoppable,” the Chinese leader said of the future of the self-ruled island, which Beijing has pledged to re-take one day.

But the two leaders “agreed Wednesday to resume on the basis of equality and respect high-level military-to-military communication,” Beijing state media said.

At the California summit, both parties agreed to establish joint government discussions on the application of artificial intelligence. Furthermore, they also established a working group on counternarcotics cooperation, according to Xinhua news agency. The two countries also pledged to enhance their efforts in increasing scheduled passenger flights between them early next year.
