The Philippine First Asylum Center (also known as P.F.A.C.) or the Vietnamese Refugee Center (VRC) was a refugee asylum camp established in 1979 by the Philippine government through the initiative of the Philippine Catholic Church, and in partnership with the United Nations High Commission for Refugees (UNHCR) and under the protection of the Western Command (WESCOM). 

P.F.A.C. was located in Puerto Princesa City along the airport on the island of Palawan- also known as the Philippines’ last frontier. The refugee center used to house eight to nine thousand Vietnamese and ethnic Chinese refugees (at a time) who fled Vietnam in search of freedom. 

Estimate over half million refugees  from 1979 until it folded in late 1995. The following year, the remaining Vietnamese asylum seekers were relocated in Santa Lourdes (14 kilometers from Puerto Princesa City Airport). The new location is called Viet Ville, which looked more like a community rather than a camp. 

In 2005, the remaining Vietnamese were eventually allowed to resettle in the United States, Australia, and Canada for compassionate reasons. Viet Ville is now one of the tourist attractions of Puerto Princesa City.
