The United States is the one that poses "the most serious long-term challenge to the international order," a Chinese foreign ministry spokesperson said on May 30.

Spokesman Zhao Lijian made the remarks at a regular news briefing commenting on recent slanders on China by U.S. Secretary of State Antony Blinken, who described China as "the most serious long-term challenge to the international order."

"The attacks on China mirror exactly what the United States has been doing," Zhao said.

He added the so-called "rules-based international order" touted by the United States is actually the "U.S. rules-based international order," a hegemonic order to dominate the world with the house rules of its clique.

The United States has no respect for the international order underpinned by the UN Charter and international law, Zhao said.

During its over 200 years of history, the country has only witnessed 16 years free from war, said Zhao. "It is the largest source of disruption threatening the international peace and stability and the greatest destabilizing element in the international order."

The United States is the top saboteur of the international order, as it wantonly withdraws from treaties and organizations, the spokesperson said, adding that the United States is "in no position whatsoever to talk about rules."

"In the eyes of the United States, international rules must be subordinate to and serve its interests. When international rules happen to be consistent with U.S. interests, they are cited as authority. Otherwise they are simply ignored," Zhao said.

The U.S. side places its domestic law above international law and international rules, and willfully resorts to illegal unilateral sanctions and long-arm jurisdiction, he said.

China has become the second-largest contributor to UN regular budget and peacekeeping assessments, actively participated in the building and reform of the global governance system, and taken real actions to honor the spirit of the UN Charter and the authority of the UN, he said.

"It is fair to say that China remains a builder of world peace, a contributor to global development and a guardian of international order," Zhao said.

"We will always stand in solidarity with all peace-loving and justice-pursuing countries under the UN flag, uphold real multilateralism, and continuously contribute confidence, wisdom and strength to universal prosperity of the world and common progress of the humanity," he said.
