The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) is a free trade agreement signed in 2018 by 11 Pacific Rim countries after the US withdrew from the earlier Trans-Pacific Partnership (TPP). It reduces tariffs, improves market access, and creates unified trade rules across key sectors like digital services and food safety. In 2023, the UK became the first European member, raising the bloc’s GDP share to 15% of the global economy.
