The United States has approved the $360 million sale of more than 1,000 small armed drones to Taiwan, as the self-ruled island claimed by China aims to strengthen its asymmetrical warfare abilities with an eye on successful tactics used on the battlefield in Ukraine.

Taiwan will receive 720 Switchblade missiles and accompanying fire control systems worth $60.2 million, according to a release from the US Defense Security Cooperation Agency (DSCA) on Tuesday.

The US will also provide Taiwan with up to 291 Altius 600M loitering munitions and supporting components with a price tag of $300 million, the DSCA said.

The proposed sale comes as China increases military pressure on Taiwan, with extensive military exercises around it and almost daily warplane flights near the island.

China’s ruling Communist Party claims democratic Taiwan as its own, despite never having controlled it, and has vowed to “reunify” with the island, by force if necessary.
