During his visit to the United States in September 1966, President Ferdinand E. Marcos of the Philippines declared in a nation-wide television interview that he knew “for a fact” that the recent resurgence of Huk guerrilla activity in his country was assisted by “agents” from Peking. A year earlier, Philippine armed forces intelligence had reported the discovery of military training centres in Bicol and the Visayas run by Chinese Communists. According to the same report, some 3,000 Chinese “subversives” in the Philippines were working closely with the Huks. Philippine constabulary chief, Brigadier General Flavio Olivares, termed the threat posed by the Chinese Communist infiltrators as more serious than that of the Huks. He noted that lax enforcement of immigration laws facilitated the entry of Chinese Communists and added that in recent years some 1,000 Chinese had gone to China, ostensibly for sentimental reasons, but had come back to the Philippines as agents. Despite the frequently partisan and self-serving complexion of some official Philippine pronouncements on the communist danger, it is impossible today to discount the significance of communist activity in the Philippines or to minimise the related problem of illegal Chinese immigration.
