Rockford, IL – The relationship between the U.S. and China is changing: China's currency is no longer pegged to the dollar. The sale of Unocal to a Chinese oil company was quashed by Congress. And there will be hearings soon in Washington about movies and music piracy in China. 16th District Congressman Don Manzullo recently returned from a visit to China. He chairs the U.S./China Interparliamentary Exchange. He spoke with WNIJ's Susan Stephens about the future of relations between the two countries.
