A Chinese mainland spokesperson on Wednesday criticized Taiwan regional leader Lai Ching-te's speech on October 10, calling his remarks "outright 'Taiwan independence' separatist claims."

Chen Binhua, a spokesperson for the State Council Taiwan Affairs Office, made the comments in response to a question about Lai's latest speech during a regular press conference.

"Lai's advocating for so-called 'cooperation with the international community' aims to 'rely on external forces to seek independence,' creating the notion of 'two Chinas' or 'one China, one Taiwan' on the international stage," Chen said.

Chen added that Lai's remarks exposed the stubborn nature of his "Taiwan independence" stance, which harms China's sovereignty and challenges the fundamental framework of the international community's adherence to the one-China principle.

Citing a series of international law documents including the Cairo Declaration and the Potsdam Proclamation – both of which have confirmed China's sovereignty over Taiwan – Chen said there is only one China in the world and Taiwan is an inalienable part of China's territory.

In 1971, the 26th session of the United Nations General Assembly adopted Resolution 2758, which, on the premise of recognizing Taiwan as part of China, returned the representation and seat of the whole of China, including Taiwan, to the Government of the People's Republic of China, Chen said.

Chen added that Taiwan's status as a part of China has never changed and will not change.

"I hope the international community will not be deceived by Lai, but instead recognize his true intentions of seeking 'Taiwan independence' and his unrealistic attempts to challenge the post-World War II international order," Chen added.
