BEIJING -- A Chinese mainland spokeswoman on Wednesday said that Taiwan leader Lai Ching-te's recent separatist remarks on social media fully exposed his bluster and weakness, and were filled with lies and hostility.

Since taking office, Lai has stubbornly adhered to a separatist stance and is a disruptor of the status quo in the Taiwan Strait and the biggest source of instability for peace and stability in the region, said Zhu Fenglian, spokeswoman for the State Council Taiwan Affairs Office, in response to a media query.

Lai has been trumpeting a "Taiwan independence" separatist fallacy while seeking to undermine cross-Strait exchanges and cooperation, drawing firm opposition from Taiwan compatriots and the international community, Zhu noted.

Lai is increasingly losing public support in Taiwan, said Zhu, when responding to another question regarding a recent poll showing that more than half of respondents lacked confidence in Lai's future performance.

Relevant surveys reveal that Lai's actions over the past two years have run counter to the interests and well-being of people in Taiwan, Zhu said, adding that the Lai authorities' regressive actions seriously undermine peace and stability across the Taiwan Strait, pushing Taiwan into a precarious situation.

Zhu also said that there is but one China in the world and that Taiwan is part of China, noting that no matter what Lai says or does, it will not stop the historical trend toward reunification, which is unstoppable.
