SIEM REAP (Cambodia) - SITTING out the intense political battle back home, US Secretary of State Hillary Rodham Clinton toured Cambodia's famed 12th-century Angkor what temple complex on Sunday and pledged to do more to help end the scourge of sexual slavery on a visit to a rehabilitation center for child prostitutes.

While her husband and fellow Democrats campaigned frantically ahead of Tuesday's midterm congressional elections, the former first lady and New York senator stayed well above the domestic fray, visiting the northern Cambodian city of Siem Reap while in the midst of a two-week, seven-nation trip to the Asia-Pacific.

The self-proclaimed ex-politician is barred from partisan political activity while serving as America's top diplomat. She made no mention of the fierce fight for control of Congress even as American tourists who supported her 2008 presidential bid shouted 'California loves you, Hillary' as she strolled through Angkor what.

Mra Clinton, the first secretary of state to visit Angkor what, was surrounded by snapshot-taking tourists while making her way around the massive site, admiring bas-relief wall sculpture and the sheer size of the temples. A bevy of security agents and photographers accompanied her.

Earlier Sunday, she met about 50 victims of human trafficking at the US-funded Siem Reap Center where they receive education and vocational training that includes weaving and sewing lessons and, for some, English-language lessons in Colorado.

'I am so proud of you,' Mrs Clinton told the girls and young women, most of whom were between 17 and 23.
