The Trump administration has approved the sale of 66 F-16 fighters to Taiwan in a move expected to anger Beijing.

Taiwan will get the latest version of the Lockheed Martin-built fighter, the F-16C/D Block 70, in the $8bn deal, the state department said.

Mike Pompeo, secretary of state, said in a statement that president Donald Trump had green-lighted the proposed sale after Congress was notified last week.

The F-16s “are deeply consistent with the arrangements, the historical relationship between the United States and China”, Pompeo said.

“Our actions are consistent with past US policy. We are simply following through on the commitments we’ve made to all of the parties.”

Taiwan’s plan to upgrade its air defences comes amid increasing Chinese military incursions into its air space.

Beijing regards Taiwan as a part of China awaiting reunification, but the island is self-ruled and is a close ally of the United States.

In a statement, the Defense Security Cooperation Agency, which oversees US foreign military sales, said Taiwan’s purchase of the F-16s “will not alter the basic military balance in the region”.

“This proposed sale will contribute to the recipient’s capability to provide for the defense of its airspace, regional security, and interoperability with the United States.”

On Monday, China’s foreign ministry spokesperson, Geng Shuang, said US arms sales to Taiwan “severely violate” agreements between Washington and Beijing and “constitute severe interference in China’s internal affairs.”

The United States should “immediately cancel the planned arms sales, and stop selling weapons and military contact with Taiwan,” he said. “Otherwise, the US will have to bear all the consequences.”

In Tapei, president Tsai Ing-wen said the sale would help Taiwan build a new air force and boost its air defense capacity. In a post on Facebook, Tsai said she was grateful for Washington’s “continuous support” for Taiwan’s national defence.

Taiwan already has a fleet of old-model F-16s purchased in 1992, which have undergone several upgrades.

Lockheed Martin said the newest version, the F-16 Block 70/72, included new avionics, weapons and radar technologies. It was also structurally stronger, the company said, so that it “can fly and fight to 2070 and beyond.”

The approval of the sale comes as Washington and Beijing face off in tough trade negotiations that economists say are hurting both of the superpowers, as well as dragging down the global economy.
