After Mexico's Ratification, the United Kingdom Accedes to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP)

• Following Mexico's ratification, the United Kingdom's accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) enters into force on June 22, 2026
• Trade and investment between both countries is expected to increase under the agreement, driven by tariff liberalization of goods and rules of origin cumulation

The Ministries of Foreign Affairs and Economy announce that, following Mexico's ratification, the United Kingdom's accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) entered into force on June 22, allowing both countries to apply the agreement's provisions to one another.

The CPTPP is a trade agreement comprising 12 countries in the Americas, Asia, Oceania, and Europe: Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, Vietnam, and, as of today, the United Kingdom. Mexico is a founding member of the CPTPP, which has been in force in the country since December 30, 2018. With the UK's accession now in effect, both countries will be able to benefit from the agreement's provisions, strengthening the bilateral economic relationship.

Both countries currently trade primarily in high-value-added goods such as industrial machinery and equipment, as well as vehicles and auto parts. Under the CPTPP, industrial and agri-food products will be tariff-free between Mexico and the United Kingdom, enabling further trade expansion. Origin cumulation provisions in the agreement can also broaden both countries' participation in each other's value chains. The agreement will also help develop priority sectors under the Plan México initiative - including automotive, aerospace, and pharmaceutical - by attracting investment into Mexico and promoting technology transfer to boost production.

Against a backdrop of global supply chain reconfiguration and the search for more diversified markets, the UK's accession taking effect consolidates Mexico's role as a global trade and investment platform, deepening its economic ties with Europe, Asia-Pacific, and the Americas through a shared set of trade rules. The CPTPP places Mexico and the United Kingdom in a new sphere of economic cooperation that will expand trade and investment between the two countries, which in 2025 alone reached $6.293 billion USD.
