Alfonso Garcia Robles explained Mexico’s position toward the proliferation of nuclear weapons, the Mexican delegation’s position toward the NPT draft, and a comparison between the Treaty of Tlatelolco and the NPT draft. He explained that the Mexican delegation favored the NPT draft but wanted to make minor language modifications and include an explicit reference to the UN Charter’s articles on the use of force, especially Articles 2 (IV) and 26. Garcia Robles also explained why he thought the Treaty of Tlatelolco was “superior” to the NPT draft as a response to nuclear risks. He argued that the regional treaty better addressed nuclear threats than the NPT draft because it included more constraints on nuclear powers, a more precise definition of a nuclear weapon, and a more institutionalized system of controls.
