The latest remarks from China's top political advisor Wang Yang have served to once again hammer home the point that Beijing's resolve to defend the nation's sovereignty and territorial integrity and throttle any attempts to split Taiwan from the motherland is ironclad.

Addressing the 13th Straits Forum in Xiamen, East China's Fujian province, on Saturday, Wang, a member of the Standing Committee of the Political Bureau of the CPC Central Committee and chairman of the National Committee of the Chinese People's Political Consultative Conference, said resolving the Taiwan question and realizing China's complete reunification is a historic mission and an unshakable commitment of the Communist Party of China.

"We have full confidence in achieving the goal," he said, stressing that the Chinese mainland will strive for peaceful reunification with utmost sincerity and efforts, but it will never leave any space for separatist activities aimed at "Taiwan independence".

Wang also pledged efforts to promote the peaceful and integrated development of cross-Straits relations and to improve the systems and policies which safeguard the well-being of Taiwan compatriots and ensure that they enjoy the same treatment on the mainland as local residents.

The wide participation of people across the Taiwan Straits in the forum both online and offline indicates the unstoppable momentum of cross-Straits exchanges and cooperation. It also serves as a barometer showing that peace and reunification are the common aspirations of the Chinese people.

Wang's message was a timely reminder to the Democratic Progressive Party administration on the island that its pro-independence stance is unpopular. Its attempts to play with fire and sabotage the one-China principle are doomed to fail.

On Friday, Nicaragua severed its so-called diplomatic ties with the Chinese island and signed a joint communique with Beijing on the resumption of diplomatic relations.

By making the right decision to recognize the one-China principle, Nicaragua has followed some other Central American countries in choosing to stand on the right side of history. In recent years, Costa Rica, Panama, Dominica and El Salvador have one after another severed official ties with the Chinese island and established diplomatic ties with Beijing. That is the right choice.

All this shows the one-China principle accords with the will of the people and the trend of the times, and is unstoppable.

The Nicaraguan move should teach the Taiwan administration a lesson that colluding with foreign forces, the United States in particular, and challenging the one-China principle will lead to nothing but a dead end.

The DPP should change course and return to the one-China framework and strengthen cross-Straits cooperation to promote the well-being of Taiwan compatriots.
