In November 1980, the just elected Reagan administration and the Khmer
Rouge made direct contact when Dr. Ray Cline, a former deputy director
of the CIA, secretly visited a Khmer Rouge operational headquarters
inside Cambodia. Cline was then a foreign policy adviser on
President-elect Reagan's transitional team. Within a year, according to
Washington sources, 50 CIA agents were running Washington's Cambodia
operation from Thailand. The dividing line between the international
relief operation and the US war became more and more confused. For
example, a Defense Intelligence Agency colonel was appointed "security
liaison officer" between the United Nations Border Relief Operation
(UNBRO) and the Displaced Persons Protection Unit (DPPU). In
Washington, sources revealed him as a link between the US government
and the Khmer Rouge.
