Trade ministers from the Regional Comprehensive Economic Partnership (RCEP) have established an ad hoc accession working group to evaluate bids from Hong Kong, Chile, Sri Lanka, and Bangladesh. This move signals a potential expansion of the world's largest free-trade area, which currently accounts for 30% of global GDP.
Why it matters
Accession could eventually reduce tariffs on nearly all goods among signatories, creating new market access opportunities and supply chain efficiencies for businesses operating within these economies. The potential inclusion of these nations builds upon the bloc's role in facilitating regional trade flow.
The RCEP bloc, which generates 30% of global GDP, recorded $5.6 trillion in export-import activities during 2024. This follows 2025 data showing Hong Kong's two-way merchandise trade with ASEAN totaled $154.5 billion.
The players
RCEP
A massive regional trade bloc currently accounting for 30% of global GDP and seeking to phase out tariffs among its members.
Hong Kong
A major global financial and logistics hub with significant two-way trade volumes currently seeking RCEP membership.
The details
The newly formed ad hoc working group will manage the technical accession processes required for each applicant to align with RCEP trade rules. By expanding, the bloc aims to further its long-term plan to eliminate tariffs across virtually all goods for member nations. These discussions occur behind closed doors, leaving the specifics of individual entry negotiations to be determined by the committee.
Timeline
2024 marked the year RCEP export-import activities reached $5.6 trillion.
2025 saw Hong Kong report $154.5 billion in two-way merchandise trade with ASEAN.
September 21, 2026, ministers met in the Philippines to authorize the new accession working group.
Market Landscape
The potential accession of new members follows the established structure of the Regional Comprehensive Economic Partnership agreement. This expansion attempt reflects the bloc's ongoing strategy to scale its influence beyond the original signatories after India previously withdrew from negotiations.
Operators should monitor future updates from the working group, as successful accession will eventually harmonize tariff structures across these new markets. Firms with supply chains in Hong Kong, Chile, Sri Lanka, or Bangladesh should track these developments for potential changes in trade costs.
The takeaway
The initiation of formal accession talks signals a significant push to widen the RCEP's reach across four distinct economies. Businesses should monitor the working group's progress for future changes to trade tariffs and market entry requirements in these regions.
