Mexico increased its international presence during López Portillo: in addition to becoming the world's fourth oil exporter, Mexico restarted relations with the post Franco-Spain in 1977, allowed Pope John Paul II to visit Mexico, welcomed American president Jimmy Carter and broke relations with Somoza and supported the Sandinista National Liberation Front in its rebellion against the United States supported government. López Portillo also proposed the Plan Mundial de Energéticos in 1979 and summoned a North-South World Summit in Cancún in 1981 to seek solutions to social problems. In 1979, the PRI founded the COPPPAL, the Permanent Conference of Political Parties of Latin America and the Caribbean, an organization created "to defend democracy and all lawful political institutions and to support their development and improvement to strengthen the principle of self determination of the peoples of Latin America and the Caribbean".
