The UK and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP)

Business guidance, treaty information and other documents to help you understand the UK’s accession to the CPTPP.

The UK concluded negotiations to join the CPTPP on 31 March 2023 and signed the Protocol of Accession on 16 July 2023. Entry into force of the agreement will take place once the UK and CPTPP Parties have finished their legislative processes. We expect this to happen in the second half of 2024.

The CPTPP is a Treaty incorporating, by reference, the provisions of the original Trans-Pacific Partnership (TPP) signed on 4 February 2016 in Auckland, New Zealand, with certain provisions suspended. The CPTPP text, setting out the incorporations and suspensions, can be found via the website of the Depositary, New Zealand. The UK’s Protocol of Accession to the CPTPP can be found below.
