Acting on the recommendation of the Committee on Foreign Investment, chaired by Treasury Secretary Tim Geithner, President Obama directed Ralls Corp. September 28 to divest its interest in the four wind farms it purchased earlier this year near the Naval Weapons Systems Training Facility Boardman’s restricted airspace in Oregon. The company is owned by Chinese nationals and is affiliated with a Chinese construction equipment company that manufactures wind turbines. Though the Treasury Department claimed that the decision does not represent a precedent for evaluations of future foreign direct investment from China, some argue that continuing U.S.-China renewable energy trade disputes may have influenced policy makers. Ralls Corp. filed a suit September 26 in the District Court for the District of Columbia against the committee challenging restrictions imposed on it while the committee reviewed the transaction.
