Tsai says Taiwan bolstering military ties with US amid threats from China

Taiwan is bolstering its military ties with the United States and will cooperate even more closely with it and other friendly nations to deal with "authoritarian expansionism", President Tsai Ing-wen told visiting US lawmakers.

The United States, like most countries, has no formal diplomatic ties with Chinese-claimed Taiwan but is the island's most important international backer and arms supplier, a consistent source of friction in Sino-US relations.

While the United States no longer maintains military bases in Taiwan, the two have a good military relationship that has become closer as China steps up pressure to try and force Taiwan to accept Chinese sovereignty.

"Taiwan and the United States continue to bolster military exchanges, and going forward Taiwan will cooperate even more actively with the United States and other democratic partners to confront such global challenges as authoritarian expansionism and climate change," Tsai told the lawmakers at her office in Taipei.

She gave no details.
