Ms. Mu Sochua is a member of a new generation of women who are working their way into the political systems of countries across Asia and elsewhere, from local councils to national assemblies and cabinet positions.

A former minister of women’s affairs, she did as much as anyone to put women’s issues on the agenda of Cambodia as it emerged in the 1990s from decades of war and mass killings. But she lost her public platform in 2004 when she broke with the government, and she is now finding it as difficult to promote her ideas as it is to simply gain attention as a candidate.
