Following the recent economic crisis, concerns over the revival of trade protectionism have surfaced, with some countries imposing or threatening to impose highly trade-distorting legislation to help their domestic industries compete in world markets, raising the spectre of a potential trade war.

It also looks at the proposed legislations, and whether they are in conflict with international trade laws.
