RCEP's Rules and ASEAN's China Strategy

A recent statement from Japan's Ambassador to ASEAN has drawn attention to the internal workings of the world's largest trade pact. According to a report from Antara News, Ambassador Yonetani Koji argued that the Regional Comprehensive Economic Partnership (RCEP) requires stronger rules to handle growing trade challenges. This call is more than a technical adjustment; it speaks to the core strategic purpose of the agreement and how its members, including the ten ASEAN nations, manage their relationships within the bloc, especially concerning China.

The RCEP Framework

RCEP brings together the ASEAN member states with five key partners: Australia, China, Japan, New Zealand, and South Korea. Its creation was a landmark achievement in regional economic cooperation, aimed at lowering tariffs, standardizing customs procedures, and promoting investment. The agreement established a single set of rules of origin for the entire bloc, a move designed to simplify supply chains and reduce costs for businesses operating across the region.

However, the agreement was the result of extensive negotiations among countries with vastly different economic models and priorities. To achieve consensus, RCEP was designed with a degree of flexibility. Compared to other major trade agreements like the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), RCEP's provisions on areas such as labor rights, environmental protection, and the operations of state-owned enterprises are less demanding. This pragmatism was instrumental in getting the deal signed, but Japan's recent statement suggests a growing debate over whether this initial framework is sufficient for the long term.

Managing Structural Dependency

The discussion about RCEP's rules is deeply connected to ASEAN's economic relationship with China. Over the past two decades, China has become the indispensable economic partner for most of Southeast Asia. Supply chains are deeply integrated, and trade volumes have made this interdependence a permanent aspect of the regional economy. As the book ASEAN Rising explains, this trade depth is now a structural feature, not a cyclical one.

This reality presents a complex policy challenge for Southeast Asian governments. The goal is not to decouple from China, but to establish a relationship that is both prosperous and balanced. The book frames the central task for policymakers succinctly, noting that "the question for ASEAN governments is no longer whether to engage, but how to manage dependency without losing optionality." Stronger institutional frameworks are a primary tool for achieving this balance. A more robust set of rules within RCEP could provide a more predictable and transparent environment for all members, helping to ensure that trade is conducted on a level playing field. It would shift the basis of the economic relationship from one primarily defined by scale and gravity to one governed by a mutually agreed-upon legal structure.

Institutions and Capital

For global capital, the quality of institutions is a decisive factor in making investment decisions. Clear rules, predictable enforcement, and reliable dispute resolution mechanisms reduce risk and provide the confidence needed for long-term investment. While RCEP has succeeded in creating a massive integrated market, its next evolutionary step may involve strengthening its institutional infrastructure.

Ambassador Yonetani's call for stronger rules can be interpreted in this light. A more rigorous RCEP would not just facilitate trade flows but would also serve as a signal to international investors that the region is committed to a rules-based economic order. In an era marked by geopolitical uncertainty and a global reassessment of supply chain vulnerabilities, creating a stable and predictable operating environment is a significant competitive advantage. By bolstering the rules that govern areas like digital trade, competition policy, and intellectual property, RCEP could attract the high-value, long-term capital needed for ASEAN members to advance their economic development.

What to watch

The practical consequences of this call for stronger rules will depend on the details that follow. It will be important to watch what specific proposals emerge, whether they relate to technical matters like customs procedures or more sensitive areas like government subsidies. The reactions from other RCEP signatories, including China and the diverse economies within ASEAN, will determine whether momentum builds for a more demanding agreement. The evolution of the RCEP framework will serve as a clear indicator of the region's capacity to build durable institutions that can support shared prosperity while managing complex strategic interests.
