The U.S. Trade Representative has launched a Section 301 investigation into China’s acts, policies and practices affecting trade and investment in green technologies. The United Steelworkers (“USW”) filed a petition, alleging that China is acting contrary to its WTO obligations by unfairly protecting and supporting domestic producers in a number of green technology sectors. Among the practices alleged are export restraints, prohibited subsidies, discrimination against foreign companies and imported goods, technology transfer requirements, and domestic subsidies causing serious prejudice to U.S. interests. The USW further alleged that China’s policies and practices have contributed to the substantial increase in the U.S. trade deficit with China in green technology goods. USTR is accepting comments on China’s practices until November 15.
