The visit of five more US lawmakers to Taiwan on Sunday, following the heels of US House Speaker Nancy Pelosi's provocative trip 12 days ago, serves only to further prove that Washington has been deliberately sabotaging peace across the Taiwan Straits, which justifies still more forceful counter-measures from Beijing.

Before they leave Taiwan on Monday, the five-member delegation, led by Democratic Senator Ed Markey of Massachusetts, are expected to meet the island officials and discuss "shared interests", according to US media reports.

Just as in the past 18 months alone, the US has made five rounds of arms sales to Taiwan, Sunday's trip to the island was the third round of such visit by members of the legislative branch of the US government in the past three months alone.

On May 30, US Senator Tammy Duckworth travelled to Taiwan.

The official visits, in addition to the arms sales, are blatant attempts by the US to keep challenging?China's sovereignty on the Taiwan question.

The terrible mistake that has been again repeated by US lawmakers is a clear testimony that the US is crudely interfering in China's internal affairs and supporting the "Taiwan independence" forces.

By continuing to ante up the signal that "the US is on Taiwan's side", those moves by the US side are hollowing?out the one-China policy that Washington has committed "no change" in following, and they are leading the "Taiwan independence" forces further down a dangerous path.

What the United States are doing on the Taiwan question is in a stark comparison with the rest of the world.

In the wake of Pelosi's visit, more than 160 countries and international organizations, including ASEAN countries and other regional countries, have criticized Pelosi's visit, and reiterated their commitment to the one-China principle.

On Aug 3, UN Secretary-General António Guterres said that the world body remains committed to the UN General Assembly Resolution 2758, the centerpiece of which is the one-China principle.

That principle means there is but one China in the world, the government of the People's Republic of China is the sole legal government representing the whole of China, and Taiwan is a part of China.

Just as Chinese State Councilor and Foreign Minister Wang Yi put it on Aug 5, "This is the unified voice of justice of the international community."

By turning a deaf ear to the voice of justice and breaching its own commitments, the US is abandoning itself in a wishful thinking of attempting to use the Taiwan card to contain China.

But Taiwan is China's Taiwan, and a determined China has never tolerated, and will never tolerate, anyone trampling on China's red line on the Taiwan question.

The military countermeasures taken by the Chinese People's Liberation Army in the waters around the Taiwan Island over the past few days have won popular support from the Chinese people and beyond.

It is the firm and strong will of the more than 1.4 billion Chinese people to achieve the reunification of China, a goal that China has said it will show "the utmost sincerity and make the utmost efforts" to achieve, but China will not allow Taiwan to be divided from it in whatever form.

By flagrantly playing with fire on the Taiwan question, some US politicians are making themselves enemies of the 1.4 billion Chinese people.

Supported by its people, the Chinese government will resolutely push back any provocations and will never allow any damage?to China's core interests and national rejuvenation.

The one-China principle is the overwhelming consensus of the international community. It is also the political foundation of the US-China relations.

US politicians, from whichever branch of its government, should behave themselves by refraining from further taking dangerous and provocative moves to infringe on China's sovereignty and security.

It is unwise to test the will and capacity of a nation so determined and decided in safeguarding its sovereignty and territorial integrity.
