China speeding up Taiwan unification plan: Antony Blinken

Beijing had decided the status quo was no longer acceptable, he said.

Speaking at an event at Stanford University on Monday with previous Secretary Condoleezza Rice, Blinken said that if Beijing could not achieve unification by peaceful means it would use coercion and possibly force, the BBC reported.

"That is what is profoundly disrupting the status quo and creating tremendous tensions," he said.

Blinken added that the US would honour its commitments to Taiwan and support the island's ability to defend itself.

In his opening remarks on Sunday at the Communist party Congress in Beijing, Chinese President Xi Jinping insisted that "complete reunification of our country must and will be realised".

"We will continue to strive for peaceful reunification with the greatest sincerity and the utmost effort, but we will never promise to renounce the use of force," he said.

Xi even refused to rule using force to unify with Taiwan.

China sees the self-ruled island as a part of its territory, but Taiwan sees itself as distinct from the mainland. Washington has always walked a diplomatic tightrope over the issue of Taiwan and China, the BBC reported.

Its official policy does not commit to military action on Taiwan - but US President Joe Biden has seemingly gone against this stance by repeatedly emphasizing that Washington would defend Taiwan.

Blinken's comments come as China is holding a twice-in-a-decade party congress, in which Xi is widely expected to be elected to a historic third theme in office.

Last month, Biden said US forces would defend Taiwan in the event of a Chinese attack - despite the official US policy of ambiguity on the issue.

Tensions between US and China have been high in recent months, especially after a visit to Taipei by US House of Representatives speaker Nancy Pelosi.

China conducted large-scale military exercises in response to Pelosi's visit, something Taiwan condemned as "highly provocative".
