TAIPEI: Some US federal employees will work in Taiwan government offices for up to one year under a new scheme to strengthen already close ties between Taipei and Washington, the de facto US embassy said on Wednesday.

The United States, like most countries, has no formal diplomatic ties with Chinese-claimed Taiwan, but is its most important international backer and arms supplier -- a persistent sticking point in its relations with Beijing.

Under the new Taiwan Fellowship Program, which is funded under Washington's 2023 Taiwan Fellowship Act, US federal employees will spend up to one year in intensive Mandarin language training and studies.

"Upon completion of training, the Fellows are expected to work, for up to one year, in Taiwan parliamentary offices, ministries, other agencies or offices, or organisations outside the public sector in Taiwan," the American Institute in Taiwan (AIT) said in a statement.
