António de Oliveira Salazar
Despite the authoritarian character of the regime, Portugal did not experience the same levels of international isolation as Spain did following World War II. Unlike Spain, Portugal under Salazar was accepted into the Marshall Plan (1947–1948) in return for the aid it gave to the Allies during the final stages of the war. Furthermore, also unlike Spain, it was one of the 12 founding members of the North Atlantic Treaty Organisation (NATO) in 1949, a reflection of Portugal's role as an ally against communism during the Cold War in spite of its status as the only non-democratic founder. In 1950, Portugal joined the European Payments Union and participated in the founding of the European Free Trade Association (EFTA) in 1960 and the Organisation for Economic Co-operation and Development in 1961. It joined the General Agreement on Tariffs and Trade in 1962, and finally, Portugal signed a free trade agreement with the European Economic Community in 1972, still under the auspices of the "Estado Novo".
Portugal
Portugal was one of only five European countries to remain neutral in World War II. 
From the 1940s to the 1960s, Portugal was a founding member of NATO, OECD and the European Free Trade Association (EFTA). Gradually, new economic development projects and relocation of mainland Portuguese citizens into the overseas provinces in Africa were initiated, with Angola and Mozambique, as the largest and richest overseas territories, being the main targets of those initiatives. These actions were used to affirm Portugal's status as a transcontinental nation and not as a colonial empire.
