BEIJING — A Chinese mainland spokesperson said Lai Ching-te has sent "a dangerous signal" of seeking "Taiwan independence" and making provocations to undermine cross-Strait peace and stability in his speech upon assuming the role of Taiwan region's new leader on Monday.

Chen Binhua, a spokesperson for the State Council Taiwan Affairs Office, described Lai's speech as one that stubbornly followed the "Taiwan independence" stance, want only advocated separatism, incited cross-Strait confrontation and sought independence by relying on foreign support and by force.

China must and will be reunified, Chen stressed. No matter how the situation on the island changes and who assumes the regional leader, it will not change the fact that both sides of the Strait belong to one China, or impede the historical trend of national reunification.

Chen said the mainstream public aspiration on the island is for peace and development, instead of war and recession, while Lai has ignored the public opinion, exposing his nature of being "a worker for Taiwan independence."

The current complex and grave situation across the Strait is rooted in the fact that the Democratic Progressive Party has stubbornly stuck to the separatist stance of "Taiwan independence," rejected the 1992 Consensus that embodies the one-China principle, and kept colluding with external forces to make provocations of seeking "Taiwan independence," Chen said.

Taiwan is an inalienable part of China, said Chen, stressing that "Taiwan independence" and peace across the Strait are incompatible as fire and water.

"We have firm determination to resolve the Taiwan question and realize national reunification; we have strong capabilities to safeguard national sovereignty and territorial integrity; and we will take resolute actions to fight separatist activities seeking 'Taiwan independence' and external interference," he said.

"We will never tolerate any 'Taiwan independence' separatist acts in any form," said Chen.

China must and will be reunified, Chen stressed. No matter how the situation on the island changes and who assumes the regional leader, it will not change the fact that both sides of the Strait belong to one China, or impede the historical trend of national reunification, he said.

"We will fully implement the Party's overall policy for resolving the Taiwan question in the new era, unswervingly uphold the one-China principle and the 1992 Consensus, work together with Taiwan compatriots to promote the peaceful development of cross-Strait relations and cross-Strait integrated development, and resolutely advance the reunification of the motherland," said Chen.

Also on Monday, a Chinese Foreign Ministry spokesperson said no matter how the political situation on the Taiwan island changes, it will not change the historical and legal facts that both sides of the Taiwan Strait belong to one China, and the historical trend that China will eventually be reunified and will inevitably be reunified.

Spokesperson Wang Wenbin made the remarks at a daily press briefing in response to a related query.

He said that the vast majority of countries and international and regional organizations in the world stand firmly with the Chinese government and people, and support China's just cause of opposing "Taiwan independence" and promoting reunification.

Certain politicians from a few countries engage in political manipulation and "personal shows" on Taiwan-related issues, which has seriously interfered in China's internal affairs and violated the one-China principle, said Wang. "China strongly condemns such moves and will take all necessary measures to firmly safeguard its national sovereignty and territorial integrity."

Wang said the general trend of history in unstoppable, and "Taiwan independence" is doomed to run into a dead end. There is no way out for external forces to interfere in China's internal affairs and condone and support "Taiwan independence," and "using Taiwan to contain China" is bound to fail.

"The day will come when China is completely reunified," said the spokesperson.

Regarding a query about recent statements from the US side distorting the United Nations General Assembly Resolution 2758, Wang said Taiwan has been an inalienable part of China's territory since ancient times, not a country.

The US move of reversing the course of history not only challenges China's sovereignty and territorial integrity, but also challenges international justice and conscience, as well as the post-World War II international order, Wang said, noting that "this is both absurd and dangerous."

Wang warned some people in the United States that those who challenge the one-China principle will eventually be engulfed by the trend of the times, and those who reverse the course of history will only fall into the abyss of history.
