Keane joined the BBC in 1989 as Northern Ireland Correspondent, but in August 1990 he was appointed their Southern African Correspondent, having covered the region during the early 1980s. From 1990 to 1994 Keane's reports covered the township unrest in South Africa, the first multi-racial elections following the end of apartheid, and the genocide in Rwanda. In 1995 he was appointed Asia Correspondent based in Hong Kong and two years later, after the handover, he returned to be based in the BBC's World Affairs Unit in London.
