Sun Yafang, Chairwoman of China's largest telecom equipment maker, Huawei Technologies, ranks 90th on Forbes magazine's 2010 list of The World's 100 Most Powerful Women. She is the only one on the list from the Chinese mainland.

Forbes magazine's citation says Sun, nicknamed "the market killer," leads the way at Huawei during a time when telecommunications are making a seismic shift from West to East.

Sun, 54, joined Huawei in 1992 and became chairwoman in 1998, overseeing marketing, research and development, and human resources. She also represents Huawei in the business community and communicates Huawei's overseas development and corporate commitments with government officials and state dignitaries around the globe.

Sun is credited with having spearheaded management reforms that have helped transform Huawei into a multinational and a leading vendor in the telecom industry. The achievement put her in prime position to succeed Huawei founder and CEO, Ren Zhengfei.
