Spain's foreign minister on Sunday called on European and other global leaders to enact concrete sanctions against Argentina in a bid to prod the country to fully compensate Spanish oil firm Repsol YPF SA for the expropriation of its Argentine unit.Speaking ahead of a meeting in Luxembourg on Monday with other European Union foreign ministers, Jose Manuel Garcia-Margallo said in an interview that Spain would push the region to impose sanctions on the Latin American country that include removing its preferential trade treatment. The EU is Argentina's second-largest export market after the South American trading block Mercosur.Mr. Garcia-Margallo also said Spain would seek help from multilateral organizations such as the World Bank, the International Monetary Fund and the World Trade Organization to pressure Argentina to rejoin negotiations with Repsol, Spain's largest oil company, over proper compensation for forcefully taking control of YPF SA, Argentina's leading oil-and-gas company.Mr. Garcia-Margallo's comments come as Spain strives to marshal international pressure against Argentina after the former colony, under President Cristina Kirchner, issued plans last week to expropriate 51% of YPF, leaving Repsol with a 6.4% stake.Argentina insists it has the right to exert sovereign control over its energy resources, but Spain and other leaders have said the move is illegal and demanded that Argentina provide proper compensation for the takeover. Argentine government officials didn't immediately respond to calls seeking comment. Ms. Kirchner has previously insisted she won't back down to Spanish pressure and is acting to ensure Argentina's energy supply. Opinion polls indicate most Argentines support the nationalization of YPF.While declining to provide specific details, Mr. Garcia-Margallo said additional unilateral reprisals would follow Spain's decision on Friday to effectively restrict imports of Argentine biodiesel, valued at about 750 million euros ($990 million) in 2011, according to Spain's Renewable Energy Producers Association.In the meantime, he said, Spain would continue to try to bring Argentina back to the negotiating table with Repsol.Spain unsuccessfully sought a negotiated solution well before the Argentine government's move, he added. zby
