BEIJING — China’s Defense Ministry accused the United States of turning Taiwan into a powder keg on Wednesday with its latest sales of $440 million in military equipment to the self-governing island democracy.

The U.S. State Department approved the sale of 30mm ammunition and related equipment, along with spare parts for Taiwan’s vehicles, small arms, combat weapon systems and logistical support items. Chinese Defense Ministry spokesperson Col. Tan Kefei responded that “the U.S. ignores China’s core concerns, crudely interferes in China’s internal affairs, and deliberately escalates tensions across the Taiwan Strait.”

China claims Taiwan as its own territory, to be conquered by force if necessary, and Tan said “stern representations” had been lodged with the U.S.

“This is tantamount to accelerating the transformation of Taiwan into a ‘powder keg’ and pushing the Taiwanese people into the abyss of disaster,” he said in a statement on the ministry’s website.

Using force to seek independence is wishful thinking and is doomed to failure, he added, using standard Chinese terminology, while noting that the People’s Liberation Army is always ready and would maintain peace and stability in the Taiwan Strait.

The U.S. maintains a “One China” policy under which it does not recognize Taiwan’s formal independence and has no formal diplomatic relations with the island in deference to Beijing. Nonetheless, U.S. law requires a credible defense for Taiwan and for the U.S. to treat all threats to the island as matters of ‘’grave concern.”

China regularly sends military vessels and aircraft across the center line in the Taiwan Strait that provides a buffer between the sides, as well as into Taiwan’s air defense identification zone, in an effort to intimidate the island’s 23 million people and wear down its military capabilities.

During a transit stop in the U.S. by Taiwanese President Tsai Ing-wen in April, during which she met with U.S. House Speaker Kevin McCarthy, China staged three days of large-scale drills around the island, simulating a blockade. China opposes any exchanges at the official level between Taiwan and other governments.

On Wednesday, 26 PLA aircraft and 4 Chinese ships were detected around Taiwan, the island nation’s Defense Ministry said. Aircraft, vessels and land-based missile systems were monitoring the situation, it said.

Few Taiwanese seem fazed by such displays, with the vast majority favoring maintaining the island’s current status of de facto independence. The island split from mainland China amid civil war in 1949.

In its announcement of the sale, the State Department said it “serves U.S. national, economic, and security interests by supporting the recipient’s continuing efforts to modernize its armed forces and to maintain a credible defensive capability.”

“The proposed sale will help improve the security of the recipient and assist in maintaining political stability, military balance, and economic progress in the region,” it said. The ammunition and associated equipment will maintain the effectiveness of Taiwan’s CM34 armored vehicles while “further enhancing interoperability with the United States.”

In addition to purchasing military hardware from the U.S. — with an estimated $19 billion of F-16 fighter jets and other items on backorder — Taiwan has been revitalizing its domestic defense industries, overhauling training and extending compulsory national service for all men from four months to one year.

While China’s vast military dominates Taiwan’s in almost every category, part of the island’s strategy is to hold off Chinese forces long enough for outside help to arrive.
