The US-China trade dispute is high on the ASEAN summit agenda. The bloc's leaders are set to sign an economic partnership deal at their annual meeting in Bangkok, but not all countries want Beijing's economic hegemony.
Southeast Asian leaders opened a 2-day summit in Bangkok on Saturday, with the US-China trade conflict taking center stage.
There has been less US engagement with the region since President Donald Trump came to power in 2016. Trump also pulled the US out of the Trans-Pacific Partnership (TPP), saying it was harmful for the US jobs market.
Analysts say Beijing is trying to dominate Asia-Pacific trade following Washington's retreat.
The bloc is weighing a China-drafted commercial deal — a substitute for the TPP — which would cover around half of the world's population. The Regional Comprehensive Economic Partnership (RCEP) includes all ASEAN member states — Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam — plus India, Japan, South Korea, Australia and New Zealand.
"The faster it (RCEP) gets implemented the better," Martin M Andanar, Philippines communications secretary, told reporters.
"Free trade is definitely what we need here in this region," he said, admitting that Southeast Asia was wary of a prolonged US-China trade row.
