A spokesman for China's Sany Group stressed on Sunday that the company is determined in its judiciary procedure against U.S. President Barack Obama.

Sany will persist in the lawsuit to the end and will appeal to the circuit court or the supreme court of the United States if necessary, the group's media official Yang Jian told Xinhua.

Yang said initial results had been achieved in the case in which the company's U.S.-based subsidiary Ralls Corp. last year filed a complaint against Obama and the Committee on Foreign Investment in the United States for blocking its owning of four wind farms in Oregon.

According to a court order, Count IV of the amended complaint will not be dismissed. It alleges that the president's "order regarding the acquisition of four U.S. wind farm project companies by Ralls Corporation" on Sept. 28, 2012 violates the due process clause of the fifth amendment to the United States Constitution by depriving Ralls of property without providing adequate opportunity to be heard or an adequate explanation of the reasons for the decision.

The ruling, which dismissed other counts of the complaint, said the plaintiff's opposition will be due before March 28 and defendants' reply will be due before April 4.

Sany is China's largest machinery manufacturer.

Xiang Wenbo, president of Sany Heavy Industry Co., said on Saturday that the case will have a "positive influence" on Sany's future overseas mergers and acquisitions.
