Written by Chun-Yi Lee and Michael Reilly. The CPTPP is an ambitious, wide-ranging free trade agreement (FTA) signed between Australia, Brunei Darussalam, Canada, Chile, Japan, Malaysia, Mexico, Peru, New Zealand, Singapore, and Vietnam in March 2018. The CPTPP was originally named as the Trans-Pacific Partnership and comprised twelve members. However, after the Trump administration withdrew the USA from it in 2017, the remaining eleven countries reorganised and renamed it. After leaving the EU, the UK applied to join in February 2021, followed by China and Taiwan in September. South Korea has been considering joining but has yet to do so. Countries seeking to join the bloc must negotiate tariffs and other market access conditions with each of the eleven original members.
