On Sunday, the United Kingdom officially became the 12th member of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, which includes Japan, Australia, and Canada among others. The United Kingdom is seeking to deepen relationships in the region and establish Global trade connections after leaving the European Union. Last year, the United Kingdom announced plans to join the CPTPP, which became its largest trade agreement since Brexit. The UK's membership means that starting Sunday, the UK will be able to implement CPTPP trade rules and reduce tariffs with eight of the existing 11 member countries, including Brunei, Chile, Japan, Malaysia, New Zealand, Peru, Singapore, and Vietnam. The agreement will take effect for Australia on December 24, and will apply to the final two member countries—Canada and Mexico—60 days after they approve the agreement.
