WASHINGTON (Reuters) - U.S. President Joe Biden said in an interview broadcast on Sunday that U.S forces would defend Taiwan in the event of a Chinese invasion, his most explicit statement so far on the issue.

Asked in a CBS 60 Minutes interview whether U.S. forces would defend the self-ruled island claimed by China, he replied: "Yes, if in fact, there was an unprecedented attack."

Asked to clarify if he meant that unlike in Ukraine U.S. forces, men and women, would defend Taiwan in the event of a Chinese invasion, Biden replied: "Yes."

The interview was just the latest time that Biden has appeared to go beyond long-standing stated U.S. policy on Taiwan, but his statement was clearer than previous ones about committing U.S. troops to the defend the island.

Asked to comment, a White House spokesperson said U.S. policy towards Taiwan had not changed.

"The President has said this before, including in Tokyo earlier this year. He also made clear then that our Taiwan policy hasn’t changed. That remains true," the spokesperson said.

The CBS interview with Biden was conducted last week. The president is in Britain for Queen Elizabeth's funeral on Monday.

The United States has long stuck to a policy of not making clear whether it would respond militarily to an attack on Taiwan.

In May, Biden was asked if he was willing to get involved militarily to defend Taiwan and replied https://www.reuters.com/world/biden-meets-japanese-emperor-start-visit-launch-regional-economic-plan-2022-05-23: "Yes ... That's the commitment we made."

In the 60 Minutes interview, Biden reiterated that the United States did not support Taiwanese independence and remained committed to a "One-China" policy in which Washington officially recognizes Beijing not Taipei.
