Chinas trade surplus with the United States increased by 24.5% in 2005, to $202 billion, the United States largest bilateral deficit. This bilateral deficit with China increased $40 billion in 2005, more than accounting for the entire increase in the United States non-oil trade deficit. China has prevented any appreciable increase in the value of its currency, which has caused the bilateral trade deficit to balloon for a number of years. Chinas intransigence has encouraged other Asian nations to prevent or slow increases in the value of their currencies. U.S. imports from China are six times the value of U.S. exports to China, making it the United States most imbalanced trading relationship. U.S. imports from China were $243 billion in 2005 (an increase of 24%), making China the second largest exporter of goods to the United States, behind Canada at $288 billion. At current rates of growth, China will surpass Canada and become the largest supplier of U.S. imports within the next two years.
