There is fear that if the China currency bill passes the House and becomes law, China will respond in kind and spark a trading war with the U.S. and cause another recession. The belief is that if countries, such as China, that artificially peg their currency to the U.S. dollar were to let their currency freely float on the foreign exchange market, their currency would appreciate to reflect their growing economy, making labor and the cost of goods more expensive to import. This would help stem the loss of jobs to countries where production is cheaper.
