South Korean opposition lawmakers and civil activists shout slogans and hold placards during a rally against the free trade agreement (FTA) between South Korea and the United States, in Seoul, capital of South Korea, on March 15, 2012. The FTA between South Korea and the United States took effects Thursday. However, the controversy didn't end in South Korea where the opposition has threatened to repeal it, but supporters of the bilateral deal argued it would create tens of thousands of new jobs and increase the gross domestic product (GDP) in both countries.
