Core Tip: On September 15, a representative from Vietnam formally submitted the instrument of accession to the Agreement on Fisheries Subsidies (Fish 1) at the World Trade Organization (WTO) headquarters in Switzerland. This move is significant, increasing the total number of WTO members who have ratified the agreement to 111, meeting the basic requirement for the agreement to officially come into effect globally (according to the rules, the agreement can only come into effect when two-thirds of WTO members—111 members—formally ratify it). Vietnam, Brazil, Kenya, and Tonga are the last four countries to "activate" this landmark agreement.
