The American Senate has approved a measure to give China permanent normal trade relations with the United States. Eighty-five Senators voted to support the bill. Fifteen voted against it. Debate on the bill began last week. Several attempts to block the measure were defeated. Supporters of the bill say permanent normal trade relations will further open China's markets to American businesses. Supporters also said the bill would help China join the World Trade Organization. Those who oppose the measure wanted China to first improve its human rights record and to stop threats against Taiwan.
