We do not know when Hanoi began adding to its Cambodian reserve. Since Communist recruiters were probably in Stung Treng Province in late 1960, however, students from the northeast may have been Hanoi-bound by1961. Cambodians from the southeast started up the trail in early 1962. Still other recruits came from Paris, where the French Communist Party was a predominant influence among Cambodian students. A high level defector reported that some 4000 ethnic Khmers were training in North Vietnam — apparently in 1967 — even after fairly large numbers had already gone South.
