A state-linked broadcaster in Singapore has re-appointed a businessman as its chairman three years after he quit the same post because he was too busy. Media Corp of Singapore (MediaCorp) said late on Tuesday that Kwa Chong Seng would replace Cheng Wai Keung as chairman from the start of next month. No reasons for the personnel switch were given. Mr Kwa was MediaCorp's chairman from October 1995 to March 1999, when the group was known as Singapore International Media. He stepped down from the post because of the 'demands on his time' from his membership of the Public Service Commission (PSC) and Temasek, according to reports at the time. Mr Kwa, a cousin of Deputy Prime Minister Lee Hsien Loong, is still a member of both bodies, according to officials yesterday. He is also chairman and managing director of ExxonMobil Asia Pacific, the regional arm of the US-based oil and gas company. The PSC, which Mr Kwa joined in 1997, attracts and develops talent for the city-state's civil service. Temasek, which Mr Kwa also joined in 1997 and where he is now deputy chairman, is one of the Government's main investment holding companies. Mr Kwa did not return calls seeking comment yesterday. Among the many companies in which Temasek has stakes are banking group DBS Group, flag carrier Singapore Airlines, and MediaCorp. MediaCorp and fellow state-linked media group Singapore Press Holdings between them control almost all of the domestic print, television and radio output in the country. MediaCorp, most of whose assets are in broadcasting, claims a 75 per cent market share in the free-to-air TV market and says that its radio stations are listened to by 95 per cent of listeners. The company says its channels five and eight are the country's most-watched English- and Chinese-language channels. Government ministers often make clear that the role of the domestic media is to support what they have called the process of 'nation-building'. The Acting Minister of Information Communication and the Arts, David Lim, earlier this month told an audience of media executives: 'By communicating the Government's message across to the people [the local media] has helped rally support for policies that have brought us progress and prosperity.' In 1998, Mr Kwa chaired a government-appointed panel to advise ministers on policies to boost the manufacturing sector's long-term competitiveness.
