Assuming the current members have no objection, the applicant country can proceed to file a formal request to join. This letter, as the UK has demonstrated, gets sent to New Zealand, as Wellington serves as the official repository location for the CPTPP. In the absence of a Secretariat, the CPTPP is managed through a rotating appointment of Commission Chairs. Japan is currently holding the post. (Mexico held it last year and Singapore is up for 2022. Both are serving as vice chairs of the Commission for 2021 to support Japan. The rotation is dictated by the order in which members joined the agreement.) A CPTPP Secretariat would make accession talks significantly easier. It would come with a built-in group of officials well versed in CPTPP rules and regulations, familiar with the existing membership and important sensitivities, as well as the current individuals for each member that are actively involved in various chapter activities. Secretariat staff could serve as neutral parties, shepherding new members through accession. Without a Secretariat, CPTPP accession will be started by the current chair. The chair will help members decide on the composition of a “working group” to manage the process. It may be that all aspiring members are grouped together into one working group or that members opt to hold separate working groups for each potential member. The chair of the working group(s) will be decided by members and the group(s) will include representatives from all active members. Accession to the CPTPP is not like launching FTA negotiations. The process is closer to that of joining the World Trade Organization (WTO). It will likely take some time to organize, as there is no sitting working group for members. New members are not negotiating over changes to existing rules. The nearly 600 pages of text need not be adjusted in accession. Instead, work will get underway on crafting new member’s specific schedules which include:
