A4: The CPTPP has plenty of room for growth, both among its signatories and among other interested nations. Brunei, Chile, Malaysia and Peru signed the CPTP in March 2018, but did not ratify the agreement within their national governments. Of the four, Chile is the closest; Its lower-party body approved membership in April, but its Senate has not yet ratified it, although it is expected to do so without much opposition. Brunei has remained silent on the chances of its accession before 2020 and Malaysian officials have expressed concern about its ratification. After obtaining a permit in March 2019, the Peruvian government appears to have stalled. With regard to CPTPP, the NIA was published on 21 February 2018 to help Parliament balance the costs and benefits of New Zealand`s signing of CPTPP and, on 9 March 2018, it was updated with more details on the alternative letters signed with the agreement. On October 25, 2018, New Zealand ratified the CPTPP and increased the number of countries that have officially ratified the agreement to four.  The Comprehensive and Progressive Trans-Pacific Partnership (PPCC) agreement is a free trade agreement between Canada and ten other countries in the Asia-Pacific region: Australia, Brunei, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam. Once fully implemented, the 11 countries will form a trading bloc representing 495 million consumers and 13.5% of global GDP and allowing Canada preferential access to the most important markets in Asia and Latin America. Nearly a year after it came into force, the Comprehensive and Progressive Agreement for the Trans-Pacific Partnership (CPTPP) has brought a mixed advantage to its 11 signatories. Trade flows between some countries have boomed, 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 the Asia-Pacific region.
Apart from that, the CPTPP remains an important trade agreement with scope for enlargement. On October 17, 2018, the Australian Federal Parliament passed legislation to this effect by the Senate.    Official ratification was filed on October 31, 2018.  This two-week gap made Australia the sixth signatory to submit ratification, and came into force 60 days later. During the round of negotiations, held in parallel with the Asia-Pacific Economic Cooperation Forum in Vietnam in November 2017, Canadian Prime Minister Justin Trudeau refused to sign the principle of the agreement and expressed reservations about the cultural and automotive provisions. The media in Australia, New Zealand and Japan, which strongly supported a rapid move towards an agreement, strongly criticized what they described as Canadian sabotage.  In February 2019, Canada`s Minister of International Trade Diversification, Jim Carr, delivered a keynote address at a seminar on CPTPP – Expanding Your Business Horizons, where he addresses companies that describe the use of the agreement as a gateway to more easily sharing people, goods and services.  However, Canada`s largest reserve was a conflict between the percentage of a vehicle that must come from a CPPP member country to enter duty-free, 45% less than the original TPP and 62.5% under NAFTA.
