The New Tango (El Nuevo Tango) was not shown in Argentina for a long time as it deals with the ascent of Argentinean president Hector Campora in May 1973, and features Cuban and Chilean presidents, Osvaldo Dorticos and Salvador Allende. A million people gathered on the Plaza de Mayo to acclaim the new President. One of Cámpora's first presidential actions was a granting of amnesty to political prisoners who where jailed during the dictatorship. On 28 May Argentina restored diplomatic relations with Cuba, which then received Argentine aid - such as food and industrial products - to break the United States embargo against Cuba.
