EU, U.S. step up WTO action in Argentina trade row

 The European Union and the United States stepped up their fight against Argentine trade practices on Thursday, formally requesting the World Trade Organization rule on whether the South American country's import restrictions are illegal.
The move followed similar challenges from Japan and Mexico, meaning Buenos Aires is now embroiled in disputes with four major trade partners, who say its rules discriminate against foreign goods at a time when trade is central to their hopes of an economic recovery.
