A Chinese mainland spokesman on Wednesday voiced firm opposition to the Democratic Progressive Party authorities over the renaming of Taiwan's "General Association of Chinese Culture", calling the move an act of "de-Sinicization" aimed at advancing separatist agendas.

Speaking at a press conference, Chen Binhua, spokesman for the State Council Taiwan Affairs Office, said Chinese culture is the shared spiritual lifeblood of people on both sides of the Taiwan Strait and a strong bond that sustains national sentiment and identity.

He warned that any attempt to use a name change as a pretext to pursue "Taiwan independence" and sever the nation's cultural roots runs counter to the course of history, harms national sentiment, and will be firmly opposed by all Chinese people. "Such efforts are doomed to fail," he added.

On Tuesday, the "General Association of Chinese Culture", a non-governmental organization on the island dedicated to promoting cultural exchange, changed its English name to the "National Cultural Association of Taiwan".

Chen said the move was orchestrated by the DPP authorities to intensify "de-Sinicization" in the cultural sphere. "In essence, it seeks to sever shared cultural roots across the Taiwan Strait and create the false impression that 'Taiwan culture exists independently from Chinese culture'," he said.

He also criticized the decision to change the English name before the Chinese one, calling it a sign of "a guilty conscience" and an attempt to proceed step by step to hollow out the meaning of "Chinese" and pave the way for "Taiwan independence" separatist agendas.

"Taiwan culture is rooted in Chinese culture," Chen said, stressing that this is a fundamental fact and a widely shared consensus among Taiwan compatriots that cannot be altered or denied.
