The area is a favorite for foreign child molesters seeking children.
In 1991 a volcanic eruption of Mount Pinatubo forced an evacuation and destroyed much of the Clark Air Base, a major United States military facility located 40 miles (60 km) northwest of Manila, which closed shortly thereafter.
Most of the sex trade around the base closed at the same time due to the loss of the GI customers.
A report published in 2004 by the Vatican stated: The Philippines has a serious trafficking problem of women and children illegally recruited into the tourist industry for sexual exploitation.
Destinations within the country are Metro Manila, Angeles City, Olongapo City, towns in Bulacan, Batangas, Cebu City, Davao and Cagayan de Oro City and other sex tourist resorts such as Puerto Galera, which is notorious, Pagsanjan, Laguna, San Fernando Pampanga, and many beach resorts throughout the country.
The promise of recruiters offers women and children attractive jobs in the country or abroad, and instead they are coerced and forced and controlled into the sex industry for tourists.
There are numerous cases of child molestation that have been reported in Puerto Galera, a beach resort on Mindoro Island three hours south of Manila.
In an effort to deal with the problem, the Philippines passed R. 9208, the Anti-Trafficking in Persons Act of 2003, a penal law against human trafficking, sex tourism, sex slavery and child prostitution.
The International Federation of Red Cross and Red Crescent Societies stated in 2003 that there were more than 1.5 million street children in the Philippines and many end up in prostitution and drug trafficking in places such as Manila and Angeles City.
In 2010, an estimated 60,000 to 100,000 children in the Philippines were involved in prostitution rings, according to Minette Rimando, a spokeswoman for the U.
N.'S International Labour Organization's Manila office. The Philippines is ranked under Tier 2 Watch List in the 2009 Trafficking in Persons Report of the United States (US) State Department due to the Philippine government’s alleged failure to show evidence of progress in convicting trafficking offenders, particularly those responsible for labor trafficking.
By the late 1990s, UNICEF estimated that there are 60,000 child prostitutes in the Philippines, describing Angeles City brothels as "notorious" for offering sex with children.
In 1997, the BBC reported that UNICEF estimated many of the 200 brothels in the notorious Angeles City offer children for sex.
Angeles Mayor Francis Nepomuceno has acknowledged the problem.
