The package -- which an official said features intelligence, surveillance and reconnaissance equipment and small arms munitions -- will be drawn from the US' own reserves, allowing it to be delivered on a faster-than-usual timeline.

These are "capabilities that Taiwan will be able to use to bolster deterrence now and in the future," a Pentagon spokesperson said.

Elements of the package "address critical defensive stockpiles, multi-domain awareness, anti-armor and air defense capabilities," he added.

"We are working expeditiously to deliver the military assistance announced today."

Congress has authorized President Joe Biden to draw aid for Taiwan from American military stocks -- the same way that Washington has provided large quantities of assistance to Ukraine since Russia invaded in February 2022.

In the past year, the Chinese military has held two major drills around Taiwan, simulating targeted strikes and a blockade of the island.

China, which is an increasingly assertive diplomatic and military power, claims the democratic, self-ruled island of Taiwan as part of its territory and has vowed to take it, by force if necessary.

A statement from the White House announced the package of "defense articles and services of the Department of Defense, and military education and training, to provide assistance to Taiwan."
