What It Means in Practice
The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) is an 11-country trade pact that took effect on 30 December 2018, after the US withdrew from the original Trans-Pacific Partnership (TPP) in January 2017. The CPTPP retained the TPP with 22 specific TPP provisions suspended (mostly intellectual-property rules that the US had pushed during the original negotiation). The 11 founding members are Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam.
The CPTPP is one of the world's largest free trade areas by GDP — covering roughly 13% of global GDP and 500 million people. It is the deepest trade agreement currently in force among major economies, with substantive disciplines on goods, services, investment, intellectual property, government procurement, state-owned enterprises, labor, environment, and digital trade.
Why It Matters
The CPTPP demonstrates that ambitious multilateral remains possible without the US. The agreement was originally a centerpiece of the Obama administration's 'pivot to Asia'; when the US withdrew, observers expected the deal to collapse. Japan's leadership salvaged it, and the resulting agreement — functioning without the US — has become a substantive economic and geopolitical fact.
For partner economies, the CPTPP delivers what the lacks: reductions, market access, and binding disciplines on regulatory practices. Asian economies that joined the CPTPP have substantively integrated their goods trade in ways that IPEF cannot match.
CPTPP Accession
The United Kingdom acceded in 2024 — the first non-Pacific member and a significant geographic and political expansion. The UK accession brought the membership to 12 and demonstrated the agreement's growing extra-regional pull.
China and Taiwan have both submitted applications. The political dynamics around their potential accession remain unresolved: China's application was filed in September 2021 days before Taiwan's, partly to complicate Taiwan's path. CPTPP members are divided on China's accession (Australia, Japan, and Canada have raised concerns about Chinese compliance with the agreement's labor and SOE disciplines). Taiwan's accession remains stalled by Chinese opposition.
Ecuador, Costa Rica, Uruguay, and Indonesia have indicated interest in accession. The CPTPP requires existing member for new members.
CPTPP vs RCEP
The CPTPP and the are the two competing trade architectures of the Asia-Pacific. CPTPP is deeper: it includes tariff cuts, SOE disciplines, labor and environment provisions, digital-trade rules, and binding investor-state dispute mechanisms. is broader: it covers more population and includes China and South Korea (who are not in CPTPP).
Several countries are members of both, creating a complex overlay of obligations.
Common Misconceptions
The CPTPP is sometimes described as 'the TPP without the US.' That undersells the changes: 22 provisions were suspended (most relating to extended IP protections the US had championed), and the agreement now operates with different leadership dynamics than the US-led TPP would have.
Another misconception is that the US is likely to rejoin. The political prospects for US re-entry are poor; both major US parties have moved away from traditional trade-agreement enthusiasm, and rejoining the CPTPP would require Congress to accept market-access commitments that successive administrations have judged politically impossible.
Real-World Examples
The UK's 2024 accession added a significant European economy to the CPTPP and demonstrated that the agreement could expand beyond the Pacific Rim. Japan's CPTPP leadership has been a notable example of middle-power agency in the post-American trade order. Vietnam's CPTPP-driven economic reforms — particularly on labor rights and SOE governance — illustrate the agreement's regulatory uplift effect on developing-economy members.
Example
The UK formally joined the CPTPP on 15 December 2024, becoming the 12th member and the first European participant.
