Awwal 15, 1432 H/Feb 18, 2011, SPA -- Brazilian President Dilma Rousseff is to visit China from April 13-15 to discuss ways to reduce trade imbalances, dpa quoted a Brazilian Foreign Minister Antonio Patriota as saying on Friday. "It will be an official visit to discuss bilateral trade and investment issues, security and environmental issues and others, besides global issues," Patriota said in a radio interview. Although Brazilian imports from China have increased, he said, the South American giant continues to have a 5-billion-dollar annual surplus in trade with China, which has overtaken the United States as the main market for Brazilian exports. -- SPA
