Sany Group, China's biggest machinery maker, has said it will fight to get compensation after US President Barack Obama barred the building of wind farms near a navy base in Oregon.
He said his company would seek a "fair and square result".
Obama on Friday ordered Ralls Corp, owned by two Sany executives, to remove all property and installations from its sites within two weeks and divest all of its interests in the wind-farm project within 90 days. It is the first time in 22 years a US president has blocked a transaction as a national security risk.
The navy conducts training for bombing, electronic combat manoeuvres and develops drones in the area around the site, the base's website says.
Sany owns China's biggest machinery maker. Duan Dawei, Sany's chief financial officer, and Wu Jialiang, a vice-president of the group and general manager of Sany Electric, a group unit, own Ralls, according to court filings. Sany, based in Changsha, Hunan, is run by billionaire Liang Wengen.
