AlHijjah 26, 1432, Nov 22, 2011, SPA - South Korea's parliament ratified a free trade deal with the United States on Tuesday, the Associated Press reported. South Korean lawmakers voted 151 to 7 in favor of ratifying the landmark trade agreement in a surprise legislative session called by the ruling Grand National Party, parliamentary officials said. The pact is America's biggest free-trade agreement since the 1994 North American Free Trade Agreement with Canada and Mexico. Two-way trade between South Korea, Asia's fourth-largest economy, and the United States totaled about $90 billion last year, according to the South Korean government.
