State Nuclear Power Automation System Engineering Company (SNPAS) is a joint venture between China’s State Nuclear Power Technology Corporation (SNPTC) and Shanghai Automation Instrumentation Corporation Ltd. (SAIC). SNPTC is currently building four AP1000 reactors in China at Sanmen and Haiyang. Further AP1000 projects are anticipated in the country.

The agreement, signed in China on 15 January 2013, outlines basic terms, conditions, division of responsibility and scope of work for AP1000 I&C projects in China. With the template contract complete, Westinghouse said that the companies would "work toward project contracts."

Qiu Shaoyang, SNPAS general manager said that SNPAS will act as general I&C contractor for future Chinese AP1000 projects, with Westinghouse a major subcontractor.
