The approval comes as Beijing promises to sanction US companies involved in the sale.
The US State Department has approved the potential sale of 100 Boeing-made Harpoon Coastal Defense Systems to Taiwan in a deal worth as much as $2.37bn, the Pentagon said on Monday, just a day after China said it would impose sanctions on US companies involved in weapons’ sales to the island.
The move came days after the State Department approved the potential sale of three other weapons systems to Taiwan, including sensors, missiles and artillery with a potential value of $1.8bn.
On Monday in Beijing, a Chinese foreign ministry spokesman told reporters China will impose sanctions on Lockheed Martin, Boeing Defense, Raytheon and other US companies involved in Washington’s arms sales to Taiwan.
US State Department spokeswoman Morgan Ortagus said in a statement: “We deplore Beijing’s efforts to retaliate against US and foreign companies for their sales that support Taiwan’s legitimate self-defence requirements.”
The US and China are at loggerheads over issues from trade to human rights and the disputed South China Sea, and President Donald Trump has made a tough approach to China central to his campaign for a second term in office in elections on November 3.
The US is bound by law to provide Taiwan, a self-ruled island that is one of Asia’s most vibrant democracies, with the means to defend itself.
Beijing sees Taiwan as part of its territory and has has not ruled out the use of force to achieve reunification. It has stepped up pressure on the island since Tsai Ing-wen was first elected president in 2016, and Taiwan says it has been forced to scramble its jets scores of times this year because of Chinese airforce activity.
Monday’s formal notifications to Congress by the State Department covered the proposed sale of up to 100 Harpoon Coastal Defense Systems, which includes 400 RGM-84L-4 Harpoon Block II Surface Launched Missiles to serve as coastal defence cruise missiles.
Last week, the State Department sent notifications to Capitol Hill for the first tranche of arms sales which included truck-based rocket launchers made by Lockheed, Standoff Land Attack Missile Expanded Response missiles and related equipment made by Boeing and external sensor pods for F-16 jets.
The formal notification gives Congress 30 days to object to any sales, but this is unlikely given broad bipartisan support for the defence of Taiwan.
