A name change for the Comprehensive and Progressive Agreement for Trans-Pacific Partnership is on the agenda for a senior officials meeting in Vietnam, as the trade bloc grapples with an acronym that even its own members struggle to pronounce.

The CPTPP is a 12-nation free trade agreement whose members include New Zealand, Australia, Japan, and the United Kingdom. It originated from the Trans-Pacific Partnership, formed in 2016, and was reconstituted as the CPTPP after Donald Trump withdrew the United States from the original TPP agreement in 2017. Vietnam assumed the CPTPP chairmanship in 2026, and the first senior officials' meeting of the year opened in Hanoi on March 12 in a hybrid format, organised by Vietnam's Ministry of Industry and Trade (RNZ; ASEM Connect Vietnam; MOIT).

Deborah Elms, head of trade policy at the Heinrich Foundation in Singapore, said the name change was long overdue. The acronym is too complicated, she said, noting that "everyone trips over the acronym." A recent poll of CPTPP members asked for suggestions for a new name, with most responses along the lines of "international" or "global trade partnership," Elms said (RNZ).

The rebranding discussion reflects how far the agreement has moved from its Pacific origins. The bloc has expanded to include non-Pacific nations such as Uruguay and Britain, with others set to join. Costa Rica is about to join, according to Elms. Eight additional countries are interested in accession, and four are starting the accession process. The agreement itself runs to roughly 600 pages of legal rules, with thousands of pages of separate schedules for all members. It has not been updated since 2015, Elms said (RNZ).

Elms has also been "arguing strongly" for the creation of a CPTPP secretariat to manage the growing organisation. The bloc currently operates without a permanent administrative body, a model that becomes harder to sustain as membership grows and accession processes multiply.

The broader context here is one of institutional drift catching up with a trade agreement that was, in some respects, designed as a stopgap. The CPTPP was the salvage operation left behind when Washington walked away from the TPP. Its members kept the substantive text largely intact, suspended a handful of provisions the United States had insisted on, and gave the whole thing a new name that no one seems to like. A decade on, the legal text has not been refreshed, the membership has stretched well beyond the Pacific, and the administrative architecture consists of rotating chairmanships and ad hoc officials' meetings rather than a standing secretariat.

For New Zealand, which has invested significant diplomatic capital in the CPTPP and its predecessor, the institutional questions matter in practical terms. A secretariat would give the bloc a permanent voice in Geneva and other trade-policy capitals, something it currently lacks. A name change would be largely cosmetic, but it would signal that the agreement has outgrown its origins as a Pacific-rim deal. And an updated legal text would give members a chance to address provisions that have aged, particularly around digital trade and state-owned enterprises, areas where global practice has shifted since 2015.

None of these outcomes is guaranteed. Senior officials' meetings set agendas; they do not deliver outcomes. Vietnam's chairmanship year will be watched for whether the name-change discussion advances from a polling exercise to a formal proposal, and whether momentum builds behind the secretariat idea. With Costa Rica's accession imminent and four more countries entering the process, the pressure on the bloc's thin institutional architecture is only increasing.
