More than a dozen Taiwan human rights and women's groups formed an alliance Thursday to canvass public support and funds for an upcoming international, private tribunal on Japan's wartime subjection of women to sex slavery.

The alliance aims to send a delegation of at least 100 people to the Women's International War Crime Tribunal, to be held in Tokyo on Dec. 8-10, said lawyer Henry Chuang, the head of the alliance.

Chuang will act as prosecutor in the private tribunal on behalf of Taiwanese women who were forced or tricked into entering Japanese wartime military brothels to serve as "comfort women."

The tribunal, which has no legal power, will bring former sex slaves and their supporters together from China, North Korea, South Korea, Taiwan, the Philippines, Netherlands, Indonesia and Japan.
