In October 1979 the scientific attaché of the South African Embassy in Bonn met his Brazilian counterpart in order to propose an exchange of experiences in the nuclear field. The South African diplomat recalled the similarities between the Brazilian and South African enrichment processes and specified that the initiative of a possible cooperation had been taken by the South African Atomic Energy Board and not by the Pretoria Government, because of the cold relations between the two countries. In this cable the Brazilian Ambassador in Western Germany, Jorge Silva, asked for instructions from Minister Saraiva Guerreiro in order to reply to the South Africans.
