The much-awaited meeting, their first in-person encounter since Biden took office in 2020, comes at a time when relations between the two superpowers have particularly soured, the BBC reported.

Given the recent spike in tensions and rhetoric, the world - and America's Asian allies including India, Japan and Australia, will be closely watching the meeting scheduled to take place on Monday in Bali ahead of the G20 Summit.

This has been fuelled by Beijing's claims over self-ruled Taiwan and its increasing assertiveness in Asia.

The US has responded by restricting access to computer chip technology, which has hit China's export-driven economy which uses the tech to make and sell everything from phones to electric cars, the BBC said.

Xi has spent most of the pandemic in China and only recently began travelling overseas again.

"I'm sure we'll discuss Taiwan... and what I want to do with him when we talk is lay out... what each of our red lines are," Biden said at a press conference on Thursday after the White House confirmed the meeting.

This way they can "determine whether or not they conflict with one another… and if they do, how to resolve and how to work it out", he said. However, he also added that he was not willing to "make any fundamental concessions" about the US' policy on Taiwan.

Biden, unlike previous US presidents, has repeatedly said the US would defend Taiwan in the event of a Chinese invasion.

But the White House has always rolled back his comments, insisting that Washington's stance of "strategic ambiguity" - under which it does not commit to defending Taiwan but also does not rule out the option - remains unchanged, the BBC said.

The White House later said on Thursday that it would brief Taiwan on the results of the meeting, with national security adviser Jake Sullivan saying the aim was to make Taiwan feel "secure and comfortable" about US support.

Meanwhile, China's foreign ministry said the US should work together with China to avoid misunderstandings and misjudgements, adding that while it wants peace with the US, "the Taiwan question" is at the core of its interests.

At the Chinese Communist Party congress in October, Xi reiterated China's position on Taiwan where they would "never promise to renounce the use of force".

He said they reserved the option of "taking all measures necessary" if "outside forces" interfered with China's claims.

The US has long been walking a tightrope over Taiwan. A cornerstone of its relationship with Beijing is the One China policy, according to which Washington acknowledges only one Chinese government - in Beijing - and has no formal ties with Taiwan.

But it also maintains close relations with Taiwan and sells arms to it under the Taiwan Relations Act, which states that the US must provide the island with the means to defend itself, the report said.
