The United States and Argentina are accusing each other of unfair trade barriers before the World Trade Organization.
U.S. Trade Representative Ron Kirk announced Tuesday that the Obama administration is taking action against Argentina's habit of denying automatic licenses for imports of all goods flowing into the country.
Kirk says Argentina's arbitrary measures are keeping out more than 600 kinds of U.S. goods, everything from auto parts to laptops to paper products.
Japan and the European Union have filed similar cases with the WTO, saying Argentina is violating the rules as it tries to protect its economy.
Argentina says the U.S. has a double standard because it blocks beef and lemons from the South American country, which is now preparing its own case for the WTO.
