Us/China Trade -- NPR's Kathleen Schalch reports on the rising trade deficit between the US and China. President Clinton will discuss the problem with Chinese President Jiang Zemin this week in Washington. The United States imports far more products from China than the Chinese buy from the US. The deficit can be partly explained by trade barriers imposed against China in 1989 after the goverment's crackdown at Tianamen Square... But some economists say those barriers are hurting US business more than China and should be dropped.
