On September 9, 2010, the United Steelworkers union filed a 5,800-page petition with the Office of the United States Trade Representative challenging as unfair a long list of China’s trade practices in the renewable energy/green technology sector. The Chinese practices being challenged—including domestic and export subsidies; export taxes, export quotas and licensing procedures; domestic content requirements; and numerous others favoring its domestic interests—are ones China routinely applies to a wide range of industrial and agricultural sectors. If the U.S. government accepts the petition and challenges some or all of these practices in the World Trade Organization (WTO), the case has the potential of affecting not only the U.S. clean energy sector, but also a wide range of other U.S. interests doing business with China or concerned about Chinese competition in the global marketplace. Even commercial interests that prefer to avoid being directly involved in challenges against China may have an interest in watching and guiding the case, since the outcome could have an impact on China’s economic and trade policies across a wide spectrum of industries.
