The Comprehensive Progressive Trans-Pacific Partnership (CPTPP) is a comprehensive free trade agreement which went into force in December 2018. Its membership consists of 11 Pacific Rim countries: Australia, Canada, Japan, Mexico, New Zealand, Singapore, Vietnam, Brunei, Chile, Malaysia and Peru, together comprising roughly 13 per cent of the world’s GDP. Despite having no geographical presence in the Pacific (unless you include the British Overseas Territory the Pitcairn Islands), the UK submitted formal notice to join the CPTPP in February 2021, a centrepiece of its ‘Global Britain’ trade strategy.
