The China Nuclear International Uranium Corporation (中国国核海外铀资源开发公司) (abbreviated as Sino-U or SinoU) is a Chinese Government owned corporation involved in prospecting, and eventually mining, overseas sources of uranium.
In late 2006, SinoU was spun off from the China National Nuclear Corporation (CNNC), China's state owned nuclear processing, mining, plant operation, and research agency, where it was previously the Overseas Uranium Exploitation Department of the CNNC.
