HANOI, Vietnam (AP) — U.S. Defense Secretary Mark Esper says the United States is providing Vietnam with a surplus American ship for its coast guard.

Esper made the announcement during a speech Wednesday at the Diplomatic Academy of Vietnam, a government university in Hanoi. He said it would be provided next year, but he gave no details on payment or exact timing.

Esper also was meeting in Hanoi with senior Vietnamese government officials. It is his first visit to the country since becoming defense secretary in July.

Vietnam is one of the most vocal critics of China’s sweeping territorial claims in the South China Sea and has accused Beijing of encroaching into its waters.
