US would defend Taiwan if attacked by China, says Joe Biden

President says US's responsibility to protect island is even stronger' after Russia's invasion of Ukraine

Joe Biden has said the US would intervene militarily to defend Taiwan if it came under attack from China, in an unusually forceful presidential statement in support of self-governing that drew a defiant response from Beijing.

Speaking in Tokyo on the second day of his visit to Japan, and against the backdrop of growing concern over Chinese military activity in the region, Biden said the US's responsibility to protect the self-ruled island - which China considers a renegade province - was even stronger" after Russia's invasion of Ukraine.
