A Chinese firm has initiated legal action against US President Barak Obama, after he issued a presidential order, blocking the construction of wind farms on land owned by the firm.
Ralls Corp bought land near US navy facilities in the state of Oregon and planned to build wind farms.
However Obama blocked the construction and ordered the company to dismantle their facilities and sell the land.
Chinese-owned Ralls Corp said the president violated constitutional protection granted to land owners, and said the US government had "acted in an unlawful and unauthorised manner".
The company said that Obama had not provided proof for his claim that there is “credible evidence’ that the company’s plans could ‘impair the national security of the United States.”
