Wu Jialiang, vice president of Sany Group Co Ltd and CEO of Sany Electric-owned Ralls Corp, talks to the media in front of the federal district court in Washington on Nov 29, 2012. A preliminary court hearing in a suit brought by China's Sany Group against US President Barack Obama will start here. The Chinese company filed an amended complaint last month against Obama and the Committee on Foreign Investment in the US at the US District Court in Washington. It claims the president's order preventing it from owning four wind farms in Oregon violated the constitution. [Sun Chenbei/Asianewsphoto]
