Binondo, the oldest and one of the largest Chinatowns in the world, was the center of commerce and business activities in the city. Numerous residential and office skyscrapers are found within its medieval streets. Plans to make the Chinatown area into a business process outsourcing (BPO) hub progresses and is aggressively pursued by the city government of Manila. 30 buildings are already identified to be converted into BPO offices. These buildings are mostly located along the Escolta Street of Binondo, which are all unoccupied and can be converted into offices.
