Alfonso Garcia Robles used his address to describe the progress in the negotiations of the Treaty of Tlatelolco. For him, this treaty included the most ambitious definition of nuclear weapons compared to existing nuclear governance texts. Another innovation was the reliance on the International Atomic Energy Agency’s safeguard system to monitor compliance. Garcia Robles also explained that Latin American delegations were almost in consensus about the Treaty of Tlatelolco text except for a couple of issues. Countries did not agree on defining the territory where the treaty would apply and when it would enter into force. The Ambassador also took this opportunity to explain the Latin American efforts to obtain negative security assurances from China. Moreover, he reminded delegates that the success of the NPT would depend on balancing obligations for nuclear and non-nuclear-weapon states. Mexican representatives argued that it was necessary to include more ambitious disarmament goals in the draft of the NPT. However, they rejected proposals to condition the approval of the NPT on the existence of concrete steps toward disarmament

The memo produced by the General Directory of Nuclear and Disarmament Issues of the Argentine Foreign Ministry presents a strategy in regard to Brazil in the nuclear area, considering the meetings between Dante Caputo and Olavo Setúbal between 20 and 21 May 1985 in Buenos Aires.

In this cable to Buenos Aires, Ambassador Vazquez reports that he requested a meeting with Minister Olavo Setúbal after General Leonidas Pires Gonçalves suggested that he would support a Brazilian nuclear weapons program. Vazquez also discusses a conversation with the Brazilian Foreign Minister's chief of staff, who told Vazquez that General Leônidas Pires refuted the reports of a Brazilian atomic bomb.

This memo from the Argentine General Directorate of Nuclear Affairs and Disarmament to the South America Directorate proposes a joint Argentine-Brazilian declaration on the peaceful use of nuclear weapons. Rejecting the establishment of IAEA safeguards, the memo instead suggests a "mutual guarantee mechanism" based on cooperation and inspections on a case by case basis.
