William Zheng Wei, a former Singapore Press Holdings business editor, has been named the chief editor of the South China Morning Post's new Chinese-language Web site. His mandate? Don't carry anything controversial. Zheng's appointment was announced Monday in an internal company release by Robin Hu, the 55-year-old chief executive officer of the SCMP Group, himself a former Singapore Press Holdings executive. Hu replaced Kuok Hui Kwong last July after serving for six years as regional director in China for the Singapore Economic Development Board, a government agency, and as a senior vice president for an Internet startup.
