WASHINGTON (AFP) - US President Donald Trump has invited South-east Asian leaders to meet next month in Las Vegas, Secretary of State Mike Pompeo said on Tuesday (Feb 25), after a summit last year was scrapped.

Mr Pompeo confirmed the date when asked at a news conference whether fears over the coronavirus outbreak would delay the summit with members of the 10-nation Association of South-east Asian Nations.

"The Asean summit is still, we're working our way through it for ... the second weekend in March in Las Vegas," Mr Pompeo said.

Diplomats said that the summit would involve Mr Trump and is scheduled to take place on March 12 in the desert gambling haven.

The United States began sounding out South-east Asian leaders about visiting after Chile cancelled a Pacific Rim summit scheduled for November in the wake of major demonstrations.

Mr Trump had likewise skipped an Asean summit and parallel East Asia Summit last year in Bangkok.

He instead sent his national security adviser, Mr Robert O'Brien, in the lowest-level participation ever by the United States in the East Asia Summit.

Most Asean leaders snubbed a meeting with Mr O'Brien, sending junior officials who were of more parallel rank.

The low-level presence in Bangkok came after years of US efforts to show that the United States is committed to Asia in the face of a rising China.

In Bangkok, Mr O'Brien renewed the US call for freedom of navigation and accused China of using "intimidation" to stop Asean nations from exploiting resources in the South China Sea.
