For decades the nuclear issue constituted one of the most sensitive aspects of the relationship between Argentina and Brazil. The mutual renunciation of nuclear weapons in the '80s led to the deepening of cooperation.
The bilateral nuclear agreement with Brazil and the Quadripartite Agreement were approved by the National Congress. Since then, these mechanisms on nuclear matters with Brazil constitute a strategic pillar of the bilateral relationship with that country. Argentina has considered that the Additional Protocol is neither convenient nor necessary for our country, neither technically nor politically.
