PHNOM PENH: A summit between U.S. President Joe Biden and the leaders of the Association of Southeast Asian Nations (ASEAN) due to be held later this month has been postponed and organisers will seek a new date, Cambodia's foreign ministers have said.

"It has been postponed to a later date because some ASEAN leaders cannot attend the meeting on the proposed dates," Minister Prak Sokhonn has said. Cambodia is the current chair of ASEAN.

The United States had announced the summit would be held on March 28 and 29.
