(Reuters) - Semiconductor testing company Cohu Inc COHU.O said on Monday U.S. restrictions on China's Huawei Technologies Co Ltd is hurting its customers' business.

The United States restricted Huawei from buying U.S. goods in May, saying the firm’s equipment could be used by Beijing for spying. The move ratcheted up trade tensions between the world’s two largest economies.
