Thailand and Indonesia pledged to boost trade and investment and cooperate on cyber scam and drug trafficking crackdowns, as Southeast Asia’s two biggest economies elevated ties to a strategic partnership.

Thailand will host the two countries’ first joint trade committee meeting later this year to explore ways to strengthen economic cooperation, Prime Minister Paetongtarn Shinawatra said during a joint news conference in Bangkok on Monday alongside Indonesian President Prabowo Subianto.

Both countries will explore possible deals through their respective investment institutions, including Indonesia’s newly established wealth fund Danantara, Prabowo said. Indonesia will also open up opportunities for Thai companies to invest in its energy sector and potentially form joint ventures in food management and storage, he said.

Paetongtarn and Prabowo, who was in Bangkok for his first official visit, also said the two countries will cooperate on the defense industry and military exercises, and increase maritime and law enforcement collaboration.
