Argentine President Cristina Fernandez also swiped at Israel's reliable UN ally — the United States — at a luncheon for Syria's Bashar Assad on Friday.
"The countries who have a seat on the Security Council can violate and ignore United Nations resolutions, and only the smaller countries, or those without military or economic power, are obliged to follow them," she said.
Buenos Aires was the last stop on Assad's tour of left-leaning countries in Latin America, where he sought to deepen cooperation and trade with Cuba, Venezuela and Brazil.
Assad and Fernandez signed accords on transportation, information and culture. Last year's bilateral trade amounted to $380 million.
Argentina is seeking the arrest of top officials of Iran, Syria's close ally, on charges of masterminding the 1994 bombing of a Jewish cultural center in Buenos Aires, but Fernandez did not explicitly address the issue in her public comments.
Assad planned to meet with representatives of Argentina's 2.4 million-member Syrian community before heading next to Spain.
