NSDD 158 United States Policy in Southeast Asia (The Kampuchea Problem)

91283 THE WHITE HOUSE SECRET WASHINGTON January 9, 1985 NATIONAL SECURITY DECISION DIRECTIVE NUMBER 158 UNITED STATES POLICY IN SOUTHEAST ASIA (The Kampuchea Problem) (U) I have reviewed the interagency study on Kampuchea, NSSD 2-84. Our interests and objectives, the basic policy lines and strategy are approved as outlined below. (S) UNITED STATES INTERESTS AND OBJECTIVES -- Global as well as regional US interests are affected by the situation in Kampuchea and its outcome. To protect these interests we seek to restore a neutral Kampuchea as a buffer between Thailand and Vietnam; to minimize Soviet influence and presence in the area; and to enhance cooperation with ASEAN in ways that also enhances or does not significantly harm our China relationship. (S) KEY ELEMENTS -- Thailand -- its security interests, and stability along its border with Kampuchea -- is central. Despite differences of perception, the ASEANs all regard Thailand as the "front line" state, and its interests as paramount. China currently plays a constructive role, but Thailand should not become overly dependent on China. Thai backing for the resistance, and access through Thailand to supply resistance forces, are critical. If the resistance appeared to increase the Vietnamese threat to Thailand, however, Thai policies could change. (S) -- ASEAN's goal is a negotiated, compromise solution, leading to a Vietnamese withdrawal. A return to power by the Khmer Rouge would be unacceptable to the ASEANs. The ASEANs want us to play a greater role in supporting the non-communist resistance, in order to further their strategy and counterbalance China. (S) China provides generous military and financial support to the Khmer Rouge, and insists that it play a full role at the present time in coalition political and military affairs. China has said it will not insist on a particular postwar government in Phnom Penh, but rather accept the results of a genuine choice by the Khmer people.
