The trade pact is set to take effect in the beginning of 2019 after it is ratified by at least six member countries.
The 11 CPTPP economies make up about 13% of the global GDP.
After the US withdrew from the Trans-Pacific Partnership (TPP), the predecessor of the CPTPP, in 2017, the remaining 11 countries (Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam) agreed to maintain the deal and rename it CPTPP.
They agreed on the revised content of the agreement on January 23, 2018.
On February 21, the full text of the CPTPP was announced, which is considered a sign showing that the 11 countries are ready to sign the agreement.
According to Reuters, more than 20 provisions of the CPTPP were suspended or changed compared to the TPP.
Earlier, US President Donald Trump said his country would consider re-entering the CPTPP if the US could get a better deal.
