UN General Assembly
1970

69. The Special Committee established by the Assembly, which began its work in the capital of Mexico in 1964, has already drafted a declaration on the principles of international law referring to friendly relations and cooperation among States. I note with particular satisfaction that among them there figures the principle of nonintervention, which is defined in the draft in terms essentially similar to those approved by this Assembly at its twentieth session, when it made the most complete and precise formulation which had been achieved so far of this principle in which we Mexicans have seen, in the more than a century and a half of our existence, the cornerstone of international coexistence.
