Wang Jianzhou, Chairman of China Mobile Communications Corp. (CMCC), China's largest mobile service provider, retired in March.

Founded on April 20, 2000, the company currently has the world's largest mobile phone network and largest customer base, competing for subscribers with its two major domestic rivals, China Unicom and China Telecom, in a nation with nearly 1 billion cell phone users.

Wang, 64, was born in Wenzhou, east China's coastal Zhejiang Province. He graduated from Zhejiang University with a master's degree in engineering, and holds a doctoral degree in business administration from Hong Kong Polytechnic University.

Wang has three decades of experience in the industry. He started to work for CMCC in 2004 as general manager and has been chairman of the company since 2010. Under his leadership, the total income of CMCC increased from 192.4 billion yuan ($30.51 billion) in 2004 to 528 billion yuan ($83.74 billion) in 2011, with the number of the company's subscribers reaching 650 million in 2011, three times that in 2004. Wang was selected one of the best CEOs in the world by BusinessWeek magazine in 2007.
