Japan has called for stronger rules under the Regional Comprehensive Economic Partnership, with Ambassador to ASEAN Yonetani Koji saying the pact needs to do more to address growing trade and investment challenges.

The remarks put the focus on whether the current RCEP framework is strong enough for a more complicated regional business environment. As cross-border trade and investment face new pressures, Japan appears to be pushing for a clearer and more effective rulebook within the agreement.

A stronger set of rules could help improve consistency for companies operating across member economies. It could also support investor confidence by making regional trade arrangements more predictable as businesses deal with shifting market conditions.

The comments, reported from Jakarta, underline Japan’s interest in keeping ASEAN-linked economic cooperation resilient and responsive. They also add to the wider discussion over how RCEP should evolve to meet the region’s changing trade needs.
