The Trump administration on Monday notified Congress of plans for a multi-billion dollar sale of Harpoon missile systems to Taiwan just hours after Beijing announced sanctions on US defence contractors.
The contractors included Boeing, the lead contractor on the Taiwan deal, which is worth 2.37 billion dollars (£1.82 billion).
“The United States maintains an abiding interest in peace and stability in the Taiwan Strait and considers the security of Taiwan central to the security and stability of the broader Indo-Pacific region,” the US State Department said, while adding the sale would not alter the military balance in the region.
Harpoon missiles are capable of striking ships and land targets. Boeing says the missile uses GPS-aided inertial navigation and delivers a 500-pound blast warhead. It can target coastal defence sites, surface-to-air missile sites, exposed aircraft, ships in port, and port and industrial facilities.
Earlier on Monday, China said it was imposing sanctions on Boeing, Lockheed Martin and other US defence firms for providing weapons to Taiwan.
The ruling Communist Party claims Taiwan, which split with the mainland in 1949 during a civil war, as part of its territory and has threatened to invade. Washington promised in the 1980s to reduce and eventually end weapons sales to Taiwan but insists its dispute with Beijing must be settled peacefully.
A Chinese Foreign Ministry spokesman, Zhao Lijian, gave no details on what penalties might be imposed or when.
“In order to safeguard national interests, China decided to impose sanctions on the American companies that were involved in arms sales to Taiwan,” Mr Zhao said.
Chinese-US relations have plunged to their lowest level in decades amid disputes about security, technology, the coronavirus pandemic and human rights.
Taiwan has long been an irritant in relations. Washington has no formal relations with the island’s democratically-elected government but is its main ally. US law requires the government to ensure Taiwan can defend itself. Weapons sales to the island have increased in quantity and quality.
Beijing regularly pressures American companies including Boeing in an effort to influence US policy.
China is one of Boeing’s largest markets for commercial aircraft, which might make it vulnerable to a boycott, but Mr Zhao mentioned only Boeing’s military arm, Boeing Defence, not its civilian airliner business.
