Despite the collapse of the political situation inside Cambodia, the Cambodian People’s Party maintained its exceptional role in cooperating with the United States in searching for missing American servicemen from the Vietnam War. Amb. Quinn describes one particular tri-lateral operation involving Laos, Vietnam and Cambodia in the most remote part of northeastern Cambodia along what had been the Ho-Chi-Minh Trail during the war. The ambassador describes how this desolate area of intense, thick jungle appeared to have never been inhabited by human beings. Nonetheless, with this exceptional cooperation by all of the communist governments involved some remains, and evidence was found at crash sites and scenes of battle along the Trail.
