A landmark regional trade deal and the fight against coronavirus are the top priorities for the Prime Minister as he takes part in ASEAN talks.
Scott Morrison is made a formal address this afternoon in a virtual summit hosted by Vietnam.
Tomorrow he will be one of the signatories of a treaty creating the world's largest economic alliance.
The deal would improve access for exports of services such as telecommunications and boost ways to tackle non-tariff barriers.
The leaders were also expected to discuss tensions in the South China Sea and on the Korean Peninsula.
