Nguyen Duc, 24, who had been a conjoined twin until he was separated from his brother in 1988, recently visited Japan to again draw attention to the issue of Agent Orange victims in Vietnam.

Duc and his brother, Viet, were born in Ho Chi Minh City in 1981. A team of Japanese doctors successfully separated them in 1988.

"Had there been no war, there would have been no massive spread of defoliant, and there would have never been so many victims in Vietnam," Duc told a peace rally at Osaka City Chuo Public Hall in Osaka's Kita Ward on March 24.

He now lives with his brother, who has been bedridden since the surgery, at the hospital where they were born and raised and has a computer-related job at the facility.
