China says Taiwan, whose government rejects Beijing’s sovereignty claims, is a purely internal matter and the most sensitive and important issue in relations with the United States.
In Beijing, China’s Taiwan Affairs Office expressed anger at the bills, which President Joe Biden said he would sign into law on Wednesday.
The bills “send the wrong signal to Taiwan independence separatist forces, and we are resolutely opposed to it”, spokesperson Zhu Fenglian told reporters.
“We urge the United States to take concrete actions to fulfil its commitment not to support Taiwan independence and to stop arming Taiwan in any way,” she added.
Taiwan has complained for the past four years of stepped-up Chinese military activity near the island, including almost daily missions by Chinese warplanes and warships.
Taiwan’s defence ministry said on Sunday it would discuss with the United States how to use the new funding.
Taiwan has since 2022 complained of delays in deliveries of US weapons such as Stinger anti-aircraft missiles, as manufacturers focussed on supplying Ukraine to help the country battle invading Russian forces.
