In a surprising move, Temasek Holdings said on Friday that Charles "Chip" Goodyear will replace Ho Ching as chief executive officer on October 1 this year. The former boss of the leading Anglo-Australian mining group, BHP Billiton, will be the first foreigner to run Temasek, one of two Singapore government investment companies, which had assets worth S$185 billion ($123 billion) as of March 30, 2008, according to the latest information on its website.
