BEIJING - China's Sany Group Co Ltd reiterated Saturday it will "fight to the end" in its efforts to sue US President Barack Obama for blocking its wind farm project purchase deal in the United States.

The Chinese company last month filed an amended complaint against Obama and the Committee on Foreign Investment in the United States at the US District Court in Washington, claiming that the president's order of preventing it from owning four wind farms in Oregon exceeded its constitutional rights and failed to provide detailed evidence.

A court hearing due on Nov 28 will decide whether the case will be accepted, and the company will take the case to the US Supreme Court if it's not, said Liang Wengen, board chairman of Sany, at a group interview on the sidelines of the 18th National Congress of the Communist Party of China, which opened Thursday.
