Biden Xi meeting: US and China to resume high-level military communication - BBC News
Joe Biden and Xi Jinping have agreed to restore a vital line in their San Francisco meeting.
During their meeting Xi told Biden to "stop arming Taiwan" and that the US should "reflect its position of not supporting 'Taiwan independence' in concrete actions", according to a Chinese government readout.

He also asked for US support of China's "peaceful reunification" with Taiwan.

Taiwan, which counts the US as its biggest ally, is a self-governed island that China claims as its own. It's been a huge sticking point for both sides.

One bugbear for China is what it sees as conflicting messages from the US.

The US has stuck to the One China policy, the diplomatic acknowledgement there is only one Chinese government which is Beijing. Biden reiterated this in his press conference just now. But it has also been arming Taiwan to its teeth, especially in recent months.

For decades the US has operated under "strategic ambiguity", where they are deliberately unclear about whether they would defend Taiwan in the event of an attack. But Biden has on several occasions said the US would go to Taiwan's military aid, only for officials to later row back on his statements.

It's also worth remembering that China has been sending its own conflicting messages.

It has long insisted that it wants "peaceful reunification". Most experts do not believe that China, at this moment, wants to invade Taiwan, even though some in US intelligence and military believe otherwise.

Yet, China has been ramping up its military presence in the South China Sea and its warplanes have been buzzing round Taiwan on an unprecedented basis. Beijing says it is defending its sovereignty claims in the area, but many see it as grey zone warfare designed to wear down Taiwan's defences.
