The 11-member Comprehensive and Progressive Agreement for Trans-Pacific Partnership trade pact entered into force on Sunday, creating a free trade area covering more than a tenth of the global economy.
The trade deal, signed in March, will cut tariffs on agriculture and industrial products, ease investment restrictions and enhance protection of intellectual property.
The 11 countries hope that the CPTPP will serve as a counter to growing protectionism as China and the United States engage in a trade war.
