Biden again says US would defend Taiwan if China attacks

US President Joe Biden has again said the US would defend Taiwan in the event of an attack by China.

Asked in a CBS interview if US troops would defend the island, Mr Biden said: "Yes, if in fact, there was an unprecedented attack".

The remarks prompted the White House to clarify that US policy had not changed.

Taiwan is a self-ruled island off the coast of eastern China that Beijing claims as part of its territory.

Washington has always walked a diplomatic tightrope over the issue.
