The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) is entering a new phase of development. Originally established as a trade agreement among Pacific Rim economies, the bloc is attracting interest from countries well beyond its original geographic focus.
Recent developments involving the UAE, South Korea and Argentina suggest the CPTPP is becoming increasingly attractive as governments seek to diversify trade relationships and secure access to growing international markets.
But what could this expansion mean for the future of the agreement?
New applicants reflect the CPTPP's growing appeal
Several countries have taken steps towards joining the CPTPP in recent months, including:
- United Arab Emirates: The UAE is moving closer to CPTPP membership as part of its strategy to expand its network of free trade agreements and strengthen economic ties with Asia-Pacific markets. Accession would support the country's wider trade agenda by providing access to some of the world's fastest-growing economies.
- South Korea: The government is reviewing whether to join the CPTPP to support export growth and improve the global competitiveness of Korean businesses. Officials are weighing the potential economic benefits alongside the domestic implications before deciding whether to pursue membership.
- Argentina: CPTPP membership is seen as an opportunity to diversify the country's export markets and deepen economic integration beyond its traditional regional trading relationships.
Taken together, these developments demonstrate that the CPTPP is increasingly being viewed as a platform for long-term trade diversification rather than a regional agreement limited to Pacific economies.
There is already precedent for the bloc expanding beyond its original geographic focus. In December 2024, the UK became the first country outside the Pacific region to join the CPTPP, demonstrating that membership is based on meeting the agreement's standards rather than geographical location. Its accession broadened the pact's reach into Europe and signaled that the agreement could evolve into a more global trading framework, paving the way for interest from countries such as the UAE and Argentina.
Expansion could reshape trade between members
For existing CPTPP members, additional economies create opportunities to expand market access while strengthening supply chain connections across different regions. Businesses could benefit from preferential tariff treatment across a wider range of markets, while investors may gain access to larger regional production networks.
The interest from the UAE is particularly notable because it would extend the agreement's reach into the Middle East. Argentina's application similarly reflects growing interest from Latin America outside the bloc's current membership.
As the agreement expands, it has the potential to become a more globally connected trading framework rather than one defined primarily by geography.
Membership remains a complex process
Although interest in joining the CPTPP is growing, accession is not automatic. Prospective members must negotiate with existing parties and demonstrate that they can meet the agreement's high standards across areas such as market access, trade rules and regulatory commitments.
This means expansion is likely to remain gradual. Each application is assessed individually, with existing members required to agree before a new country can accede.
For countries such as South Korea, domestic considerations also remain important. According to The Korea Times, the government is continuing to evaluate how membership could affect domestic industries while weighing the opportunities for exporters.
A broader role in global trade
As geopolitical uncertainty rises and supply chain diversification becomes increasingly important, countries are seeking trade agreements that provide access to multiple markets while reducing dependence on individual trading partners.
The applications from the UAE, South Korea and Argentina suggest the CPTPP is becoming part of that strategy. Rather than remaining a Pacific-focused agreement, it is increasingly being viewed as a platform for broader international trade integration.
This could create new opportunities over time as the agreement expands. While accession processes are likely to take several years, continued growth would increase the bloc's economic reach and strengthen its role as one of the world's most significant regional trade agreements.
