In the late 1970s and in the 1980s, the Socialist International (SI) had extensive contacts and discussion with the two powers of the Cold War, the United States and the Soviet Union, about east–west relations and arms control. Since then, the SI has admitted as member parties the Nicaraguan FSLN, the left-wing Puerto Rican Independence Party, as well as former communist parties such as the Democratic Party of the Left of Italy and the Front for the Liberation of Mozambique (FRELIMO). The SI aided social democratic parties in re-establishing themselves when dictatorship gave way to democracy in Portugal (1974) and Spain (1975). Until its 1976 Geneva Congress, the SI had few members outside Europe and no formal involvement with Latin America.
