๐Ÿ—ฃ๏ธAmbassador Juan Carlos Ojeda Viglione assumed office as Secretary-General of OPANAL on 1 January 2026, following his election by acclamation at the XXIX Special Session of the General Conference (19 December 2025), in accordance with resolution CG/E/Res.03/2025.

A career diplomat from Uruguay ๐Ÿ‡บ๐Ÿ‡พ with more than 40 years of experience, he has devoted his career to strengthening multilateralism, disarmament, and non-proliferation. He served as Uruguayโ€™s Permanent Representative to international organizations in Vienna, including the IAEA, at key moments in the global nuclear debate, and twice as Director of Multilateral Affairs at the Ministry of Foreign Affairs.

In an increasingly complex international context, his tenure for the period 2026โ€“2029 is focused on consolidating Latin America and the Caribbean as a nuclear-weapon-free zone, strengthening the Treaty of Tlatelolco, and projecting the regionโ€™s voice in key international forums.

In this video, the Secretary-General presents the four priorities that will guide his mandate: greater international visibility, strengthening the non-proliferation regime, transparent and inclusive management, and the promotion of disarmament education.
