Therefore, despite their considerable economic costs, trade barriers remain. For example, according to the U.S. International Trade Commission, the U.S. profit on lifting trade restrictions on textiles and clothing was nearly $12 billion in 2002 alone. This is a net economic profit after deduction of losses incurred by enterprises and workers in domestic industry. Nevertheless, domestic textile producers managed to convince Congress to maintain strict import restrictions. A regional trade agreement (RTA) is a treaty between two or more governments that sets out the trade rules applicable to all signatories. .
