BEIJING -- A Chinese spokesperson on Wednesday condemned the so-called Inter-Parliamentary Alliance on China (IPAC) for making provocations on Taiwan-related issues.

Chen Binhua, spokesperson for the State Council Taiwan Affairs Office, made the remarks at a press conference in response to a media query about the IPAC annual meeting held in Brussels, where Taiwan's Hsiao Bi-khim attended as a speaker.

Chen dismissed the so-called IPAC as merely a clique of anti-China elements, expressing firm opposition to its repeated interference in Taiwan-related issues.

He also slammed the Democratic Progressive Party authorities in Taiwan, noting that their collusion with such organizations to stage a farce will only add to the ridicule and bring disgrace upon themselves.

Slamming the Japanese leader's remarks on Taiwan

On the same day, China also expressed "strong dissatisfaction and resolute opposition" to egregious remarks about Taiwan made in parliament by Japan's leader, saying they severely violated the one-China principle and constituted gross interference in China's internal affairs.

"The world has only one China and Taiwan is part of China," said Chen when asked about these comments.

Chen's remarks came after Japan's leader recently made statements concerning Taiwan during a parliamentary session. These statements drew sharp criticism from China.

"Japan has committed crimes in history against the Chinese people on the Taiwan question," Chen stated, noting that during its colonial rule over Taiwan for half a century, Japan committed innumerable crimes.

The spokesperson highlighted that 80 years ago, China defeated the Japanese aggressors and restored Taiwan -- thereby ending Japan's occupation and plunder of the island.

"Today, 80 years later, should anyone attempt to challenge China's core interests and obstruct China's reunification, the Chinese government, Chinese people and Chinese military will never accept it and never tolerate it," Chen warned.

He urged Japan to "deeply reflect on history, draw lessons from history, strictly adhere to the one-China principle and the spirit of the four political documents between China and Japan, honor its political commitments on the Taiwan question, and exercise extreme caution when handling Taiwan-related matters."

The spokesperson also issued a stern warning to Taiwan's Democratic Progressive Party authorities, stating that "any scheme to rely on external forces to split Taiwan from China is doomed to fail."
