It was signed on 8 March 2018 and entered into force on 30 December 2018 following the ratification of the agreement by a majority of signatories. The pact binds its members, who account for about 13.5 percent of world merchandise trade, to 30 chapters that provide for free trade and free access to investment. Nearly a year after its entry into force, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) has provided its 11 signatories with a mixed set of benefits. Trade flows between some countries are booming, while for others they have remained stable. However, it is difficult to measure the extent to which these changes are due to the CPTPP; Other trade agreements and frictions have also influenced trade flows in Asia-Pacific. Regardless of this, the CPTPP remains an important trade deal with room for expansion. The agreement between Australia, Canada, Japan, Mexico, New Zealand and Singapore entered into force on 30 December 2018. Although its text is similar to that of the Trans-Pacific Partnership (TPP) that the United States abandoned in January 2017, the CPTPP has suspended or amended 22 of the original provisions. Many of these changes are minor, but some mark significant changes compared to the TPP. For example, two types of investment agreements that were suitable for trial after the TPP are no longer covered by the CPTPP. In addition, Chapter 18, which deals with intellectual property, has been the subject of the most comprehensive revisions. .
