Any attempt for "Taiwan independence" by any force will not way succeed, said An Fengshan, spokesman for the Taiwan Affairs Office of the State Council, on Wednesday.
The Chinese mainland strongly condemned the island's Democratic Progressive Party for indulging and supporting the separatists while acting against those who support peaceful reunification, An said.
Official contacts have been disrupted since Taiwan's current leader, Tsai Ing-wen of the Democratic Progressive Party, took office in May 2016. She refused to recognize the 1992 Consensus that affirms both sides of the Taiwan Straits belong to one China.
"Taiwan authorities' denial of the 1992 Consensus has undermined the common political foundation of the two sides and made the cross-Straits relations increasingly complex and severe since last May," he said.
An's comments came after the Democratic Progressive Party's recent movements that undermine the peaceful development of cross-Straits relations, including lowering the threshold of voting on a referendum, indulging the separatists' advocating constitutional amendment and taking away four members of Taiwan's pro-reunification New Party for investigation.
Meanwhile, Taiwan authorities' suppression and persecution of pro-reunification entities and individuals triggered an uproar on the island and the mainland.
"The current Taiwan authorities do not communicate with the mainland, and also deprive others of their right to communication," An said.
"The interference and obstruction of the cross-Straits exchanges go against the will of the people," An said commenting on the current Taiwan authorities' decision to reject Taiwan-based Kuomintang Party Vice-Chairman Tseng Yung-chuan's application to visit the mainland.
"The frequent behaviors of the Taiwan authorities indicate the lack of confidence of the 'ruling' party," said Xu Xiaodi, a researcher of Taiwan studies at the Institute for International Strategic Studies of the Central Party School of the Communist Party of China.
"Tsai and her administration are trying to test the bottom line and tolerance of the Chinese mainland, which will definitely undermine the exchanges of the peoples of the two sides. They lack vision for the development of cross-Straits relations in a long run," Xu said.
