China claims Taiwan is part of its territory and insists that waters around the island democracy come under its jurisdiction, which Taipei rejects.

Taiwan and the United States signed a memorandum of understanding in 2021 to boost maritime cooperation between their respective coast guards, but they rarely publicise joint training exercises.

That appears to be changing after the de facto US embassy in Taiwan published an undated photo last month on Facebook of a US coast guard ship sailing beside a Taiwanese coast guard vessel.

That came after Chinese ships began in June to patrol for the first time an area of the Western Pacific near Taiwan's east coast, which Taipei branded as "provocative" and "expansionism in disguise".

The US Coast Guard training from August 10-21 will focus on "small-craft operations, team coordination and maritime patrols", Taiwan's coast guard said in a statement.

The aim is to improve Taiwan's "maritime law enforcement capabilities" when operating in "complex maritime operational environments", it said.

Taiwan's coast guard declined to provide further details about the training.

China has stepped up military and coast guard activity near Taiwan in recent years, deploying fighter jets, warships and other vessels around the island on an almost daily basis.
