Nuctech Company, Ltd (同方威视技术股份有限公司, formerly 威视股份) is a Chinese partially state-owned security inspection products company, headquartered in Beijing, created in 1997 as an offshoot of Tsinghua University. Nuctech Company's parent company, Tsinghua Tongfang, is controlled by the China National Nuclear Corporation, a state-owned company that manages China's civilian and military nuclear fuel development program. Several countries have raised concerns about contracts for security scanning equipment due to the company's partial state ownership and alleged ties to the Chinese Communist Party and Chinese military.
