Prosecutors from around the world say the fight against sex trafficking is moving online as traffickers use popular websites to advertise sexual services.
They're talking about how they can crack down on the problem at an international sex trafficking summit in Waikiki.
Some said Friday they're pushing for legislation in the United States to make it illegal to use websites to solicit illegal sex.
Other law enforcement officers say the websites have helped them catch traffickers by identifying locations where there's a problem.
Prosecutors from Canada, China, Japan, Palau, the Philippines, South Korea, Taiwan and Thailand attended the summit.
American prosecutors attended from more than a dozen states including Arkansas, California, Hawaii, Illinois, Kansas, Louisiana, Massachusetts, Nebraska, New York, Nevada, Oregon, Virginia, Washington and Washington D.C.
