After US President Joe Biden and China president Xi Jinping’s talks, it was evident that there are still significant differences concerning Taiwan. 

While Biden reiterated the US' long-standing support for the "One China" policy, which recognises Beijing rather than Taipei, he also stated that he "strongly opposes unilateral efforts to change the status quo or undermine peace and stability across the Taiwan Strait," said the White House.

Xi said that those seeking independence in Taiwan and their allies in the US are "playing with fire. China is patient and seeks peaceful reunification with great sincerity and effort, but if Taiwan secessionists provoke, or even cross the red line, we must take decisive action."

Despite Biden's "very obvious concerns," a US official stated "nothing new was developed in the shape of guard rails or any other understandings" on Taiwan.

Xi objects to Washington's efforts to carve out greater space for Taiwan in the international system, and Biden's recent remarks that the US would defend Taiwan in some circumstances heightened tensions further.

China claims ownership over the self-ruled island. Beijing has pledged to take control of the island, if necessary by force.

In response to the talks, Taiwan's Foreign Ministry expressed hope that China would accept its "common responsibility" for maintaining peace across the Taiwan Strait and resolving differences through dialogue.

Biden also brought up other domestic issues that Beijing is concerned about, such as its handling of Tibet, Hong Kong, and Xinjiang, where China's policies are frequently criticised by international human rights organisations.
