Alfonso Garcia Robles explained how the Mexican delegation tried to gather the support of the Latin American countries for the NPT draft. These countries prepared and presented modifications to the NPT text, and the United States and the Soviet Union accepted some of these proposals. Garcia Robles reported that the Argentinian and Brazilian representatives said they recognized the value of the NPT but would not support it if it kept its clause prohibiting peaceful nuclear explosions. The Ambassador also reported the Soviet positive reactions toward the Treaty of Tlatelolco. Garcia Robles recounted the skepticism of some delegations toward the NPT. He recommended not to sign the NPT in 1968 unless the Soviet Union signed Protocol II of the Treaty of Tlatelolco, which includes negative security assurances.

Soviet representatives being sent to Italy, Japan, Mexico, Brazil, and Italy, are instructed to visit the head of state or the minister of foreign affairs and relay the oral declarations contained in this document. The country-specific oral declarations reinforce the Soviet position against the use of nuclear technology for militaristic objectives and object to proposed measures that would undermine the efficacy of the NPT.

Document is notifying Soviet ambassadors to visit respective heads of state and Ministers of Foreign Affairs and inform them of the Soviet position on the draft treaty of the NPT given that the 18-Nation Committee on Disarmament recently finished its deliberations on the Treaty and submitted it to the UNGA.
