Stocks fell on Tuesday on speculation that the government may continue its tightening measures after last month's imports rose to a record high and new bank lending increased.

China's imports expanded by 30.2 percent to a record 155.56 billion U.S. dollars in August, stoking concerns that surging imports may be bringing inflation into the domestic market from overseas, according to data from the National Bureau of Statistics.
