Argentina’s Foreign Ministry filed a dispute August 17 with the World Trade Organization against Spain’s biofuel import curbs, charging that the violate World Trade Organization rules and harm Argentinian exports. Argentina, the world’s top supplier of soy oil and soy-based biofuel, opposes Spain’s April Ministerial Order implementing the European Union’s renewable energy directive. The order specified that biofuels used in transportation must be met with EU fuel. The European Union agrees with Spain that the directive is compliant with WTO rules, but Argentina said that it closes the door to shipments of the fuel and is in violation of accepted international trade practices.
