Britain enters CPTPP as the pact’s first European member
Membership expanded the UK’s trade framework across the Pacific.
The UK became a member of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership on 15 December 2024. The government described it as the first European country to join the group, whose members include Japan, Vietnam, Peru and Malaysia. The milestone followed negotiations and ratification steps.
Trade preferences and commercial returns
The government projected a long-term annual economic benefit of £2bn. Achieving gains depended on companies using the agreement’s trade preferences, finding customers and meeting applicable conditions. Accession widened the rules available to British businesses trading with members, but commercial demand would determine how extensively those opportunities were used.
