U.S. Commerce Secretary Gary Locke urged China on Sunday to remain open to U.S. and other foreign technology as it ramps up investment in clean energy to fight global warming and secure its economy, accordint to Reuters. "China, given the incredible challenges that is has, should in my view be taking the best technology from wherever -- whether it's China, the United States, Europe, Japan, anywhere else," Locke said at the start of a trade mission to open doors for U.S. clean energy firms. The United States and a number of other countries have concerns about China's local innovation policies, which could restrict foreign participation in Chinese clean energy projects. -- SPA
