Help Taiwan compatriots but strictly deal with Tsai

Li Zhenguang, a professor at the Institute of Taiwan Studies, Beijing Union University

Cross-Straits relations have been at a low ebb due to the Democratic Progressive Party's pursuit of "Taiwan independence" since it took office in May 2016, and have deteriorated further after the aggressive Lai Ching-te became the island's executive head in September 2017. In a way, therefore, the live-fire drill in the Taiwan Straits on Wednesday is the mainland's response to those seeking "independence" of the island. And it is a warning that the situation will further worsen and the trouble mongers will face severe punishments once they cross the red line.

Ignoring people's interests and achievements, which the previous government paid great heed to, the Tsai Ing-wen administration on the island has refused to recognize the 1992 Consensus and thus jeopardized cross-Straits ties. So, while helping Taiwan compatriots with more favorable policies such as the latest 31 measures giving the Chinese mainland and Taiwan residents equal treatment, Beijing should deal with the Tsai administration with a firm hand and take measures to deter the separatists from creating more trouble.

As part of its political and economic agenda to curb China's rise, the United States has been stirring up tension across the Straits in recent months by, for example, passing the Taiwan Travel Act that allows "mutual visits of all levels of officials" between Washington and Taipei, and promotes the construction of a new building for the American Institute Association in Taiwan.

Also, the military drill sends a message to the US that it should stop backing the separatists on the island, because once its wrong policies prompt the separatists to cross the red line, the situation could become very difficult for even the US to handle.

The mainland has repeatedly made it clear that it seeks peaceful cross-Straits relations but only under the one-China principle. And the live-fire drill is an important strategic step to warn Taiwan separatists that they should mend their ways.
