Meanwhile an awesome economic force apeared on the Philippine landscape. Onofre D. Corpuz explains: "Our knowledge (1965) about the natives land holdings is very limited. A Spanish author (Joaquin Martinez de Zuñega) writing just after 1801 warned that all the lands of the natives were being acquired by the Chinese mestizos." This is even truer today. Elite minorities of Chinese descent control most of the resources in the Philippines. Explains Global Paradox author John Naisbitt: "As much as 70 percent of the private sectors in Singapore, Malaysia, Thailand, Indonesia, and the Philippines are controlled by minorities of Chinese descent."
