The Parliamentarians for Global Action 37th Annual Forum focused on 'The Role of Parliamentarians in Support of Peace and Security' with an overriding objective of promoting universality and implementation of the Arms Trade Treaty (ATT) and, separately, the Biological and Toxin Weapons Convention (BWC). As a result of this meeting, the San Salvador Plan of Action to Promote Universality and National Implementation of the Arms Trade Treaty was enacted. An additional goal of the 37th Annual PGA Forum was to identify linkages between the inadequate control/oversight/regulation of arms/weapons exports/imports on the one hand and the recent, serious up-tick in gang and gang-related violence in Latin America, on the other. In so doing, an assessment was made on how adherence to the ATT and other relevant international agreements/treaties may contribute, directly and/or indirectly, to positively addressing this grave situation.
