On Friday, China said that it would impose sanctions on US firms involved in a deal to sell $2.2-billion worth of tanks, missiles and related equipment to Taiwan, saying it harmed China's sovereignty and national security.
On Monday, the Pentagon said the US State Department had approved the sale of the weapons requested by Taiwan, including 108 General Dynamics Corp M1A2T Abrams tanks and 250 Stinger missiles, which are manufactured by Raytheon.
Washington said the sales would not alter the basic military balance in the region, but Beijing, a major U.S. security rival with which Washington has been engaged in a year-long trade war, has demanded the deal be revoked.
China’s latest statement came as Taiwan President Tsai Ing-wen was in New York en route to visit four Caribbean allies, a trip that has also incensed China.
A spokesman for China’s foreign ministry said the U.S. arms sale constituted a serious violation of international law and basic norms governing international relations.
The spokesman, Geng Shuang, also called the sale a serious violation of the “one-China” principle, under which the United States officially recognizes Beijing and not Taipei.
“To safeguard our national interests, China will impose sanctions on the U.S. enterprises involved in the above-mentioned arms sales to Taiwan,” Geng said.
The State Department declined to comment and the US firms involved in the Taiwan arms deal did not immediately respond.
China deems Taiwan a wayward province and has never renounced the use of force to bring the island under its control.
On a visit to Budapest on Friday, China’s top diplomat Wang Yi warned Washington it should “not play with fire” on the question of Taiwan.
He said no foreign force could stop the reunification of China and no foreign force should try to intervene.
“We urge the U.S. to fully recognize the gravity of the Taiwan question ... (and) not to play with fire on the question of Taiwan,” Wang told a news conference via an interpreter.
“The cultural and political differences across the Taiwan Strait only grow wider by the day; and each day that Taiwan chooses the freedom of speech, human rights, the rule of law, is a day that we drift farther from the influences of authoritarianism,” she said, referring to China.
The U.S. State Department has said there has been no change in the U.S. one-China policy and that it allowed such transit stops “out of consideration for the safety, comfort, convenience and dignity of the passenger.”
