Taiwan's changing politics won't affect meaning of 'One China' principle: Xi

China's President Xi Jinping said Taiwan's changing politics would not affect the meaning of the 'One China' principle, the Chinese state radio broadcaster said on Tuesday.

Beijing has withheld official communication with the government of Democratic Progressive Party leader and President Tsai Ing-wen, until it agrees to recognise the 'One China' policy.

China says Taiwan is part of one China, ruled by Beijing. It regards the island as a renegade province, to be united by force if necessary, and ties have become strained since Tsai took office in May.

The previous Nationalist administration agreed to recognise the "1992 consensus", which states that there is only one China, with each side having its own interpretation of what that means.

The Nationalist Party chairwoman Hung Hsiu-chu visits Beijing this week, and met Xi on Tuesday.
