The China Orient Telecommunications Satellite Co. of Beijing (part of the Ministry of Posts and Telecommunications) contracted Lockheed Martin Astro Space to build the A2100 class Zhongwei I (Chinastar 1). The satellite was launched in the spring of 1998 by CZ-3B and has a mass of 2984 kg (1418 kg BOL). It will serve China, southeast Asia, India and Korea. It entered a supersynchronous orbit, later lowered to geostationary. However, the orbit remained eccentric.

China Orient was later merged into China Satcom and Zhongwei 1 was renamed Zhongxing 5A. China DBSAT was founded Dec 2007 and merged into China Satcom in Apr 2009.
