Washington is pursuing the sale of more than US$2 billion worth of tanks and weapons to Taiwan, four people familiar with the negotiations said, in a move likely to anger Beijing as the trade war between the world’s two biggest economies escalates. An informal notification of the proposed sale has been sent to the US Congress, the four sources said on condition of anonymity because they were not authorised to speak about the possible deal. The potential sale included 108 General Dynamics M1A2 Abrams tanks worth around US$2 billion as well as anti-tank and anti-aircraft munitions, three of the sources said. Taiwan has been interested in refreshing its existing US-made battle tank inventory which includes M60 Patton tanks. Washington is the main arms supplier to Taiwan, the self-governed island that Beijing deems its own. China has never renounced the use of force to bring Taiwan under its control. Taiwanese President Tsai Ing-wen said in March that the United States was responding positively to Taipei’s requests for new arms sales to bolster its defences in the face of pressure from Beijing. The United States has no formal ties with Taiwan, but is bound by law to help provide it with the means to defend itself. China and the United States are engaged in a fierce trade war, with clashes over Taiwan and the South China Sea exacerbating tensions. A spokesman for the State Department, which oversees foreign military sales, said that the US government did not comment on or confirm potential or pending arms sales or transfers before they had been formally notified to Congress.

In addition, the notifications included 1,240 TOW anti-tank missiles worth as much as US$299 million, one of the sources said, adding that the notification also included 250 stinger missiles worth as much as US$223 million. Stingers are often used in man-portable anti-aircraft weapons systems. In 2018, US President Donald Trump’s administration rolled out a long-awaited overhaul of US arms export policy aimed at expanding sales to allies, saying it would bolster American military sales and create jobs at home. Last week, the Pentagon announced it would sell 34 ScanEagle drones, made by Boeing, to the governments of Malaysia, Indonesia, the Philippines and Vietnam for US$47 million. The drones would afford greater intelligence-gathering capabilities, potentially curbing Chinese activity in the region. China claims almost all of the strategic South China Sea and frequently lambasts the United States and its allies over naval operations near Chinese-occupied islands. Brunei, Indonesia, Malaysia, the Philippines, Taiwan and Vietnam have competing claims. China sends message at regional security forum amid tight media control Last weekend, at the Shangri-La Dialogue in Singapore, Chinese Defence Minister Wei Fenghe warned the United States not to meddle in security disputes over Taiwan and the South China Sea. Acting US defence secretary Patrick Shanahan told the forum that the United States would no longer “tiptoe” around Chinese behaviour in Asia.
