Biden, China's Xi expected to meet virtually on Monday

US President Joe Biden and Chinese leader Xi Jinping are expected to hold a virtual summit on Monday, sources said, amid tensions over trade, human rights and military activities.

Washington and Beijing have been sparring on issues from the origins of the Covid-19 pandemic to China's expanding nuclear arsenal. US officials believe direct engagement with Xi is the best way to prevent the relationship between the world's two biggest economies from spiralling toward conflict.

Beijing is also keen to avoid confrontation and focus on "positive competition," while pushing for cooperation on issues such the climate crisis and ending the coronavirus pandemic, said one Chinese official.

A framework deal on boosting cooperation to tackle climate change, unveiled by the world's two largest economies at the UN climate conference in Scotland, sent "quite a positive signal" for the upcoming summit, the official said.

"We view US-China competition like a golf game, where each side focuses on its own better performance, not like a boxing game, where both sides try to knock each other out," the official added.

The White House declined to comment on Thursday.

Separately, Biden will address the Asia Pacific Economic Conference leaders' summit in an online appearance on Friday morning, the White House said.

Xi is likely to invite the US president to attend the 2022 Winter Olympics in Beijing, CNBC reported on Thursday, citing two people familiar with the matter.

Such a request could put Biden in an uncomfortable spot as he presses China on human rights. Biden is unlikely to go to Beijing for any kind of meeting; the US president did not attend the Summer Olympics in Tokyo, a key American ally.

Biden and Xi last spoke on Sept 9, a 90-minute conversation that a senior US official said focused on economic issues, climate change and Covid-19.

Biden has been eager to hold face-to-face talks with Xi to try to reduce tensions with Beijing over Taiwan and a host of other issues.

US officials had wanted Biden to meet Xi on the sidelines of a G20 summit in Rome two weeks ago, but Xi has not travelled outside of China since the pandemic broke out 21 months ago.

The latest Biden-Xi virtual meeting was agreed to in principle last month during talks in Zurich between China's top diplomat, Yang Jiechi, and US national security adviser Jake Sullivan, who raised concerns about Chinese actions in the South China Sea, as well as human rights and Beijing's stances on Hong Kong, Xinjiang and Taiwan.

A senior administration official said there was nothing to announce yet. "We have an agreement in principle to have a virtual bilateral meeting before the end of the year. Working-level discussions are under way to confirm details," the official said.

The White House has characterised the upcoming meeting as part of ongoing US efforts to "responsibly manage" competition between the two countries.
