The Document Memorandum for: Director of Central Intelligence Via: D slash DCI slash NI From: James R. Lilley, National Intelligence Officer for China Subject: Chinese and the Two‑Front Challenge Action Requested: None. This memorandum is for your information. Background: This provides you with our reasoning on why Chinese resistance against the Soviets would be weakened by a People’s Republic of China invasion attempt against Taiwan. It is in response to a question you posed at the Sino‑Soviet briefing on twenty‑eighth June. Coordination: This was prepared by the Office of Soviet and Russian Affairs. Defense Intelligence Agency has informally coordinated. Attachment: Forces Available to China for an Invasion of Taiwan 1. During our Sino‑Soviet briefing, you asked about China’s ability to invade Taiwan and still maintain its northern defenses. 2. The forces China would commit to an invasion of Taiwan would depend to some degree on the Sino‑Soviet border situation. Central Intelligence Agency and Defense Intelligence Agency analysts agree that the equivalent of some sixty divisions probably would be needed for a successful invasion. Although China fields a total of forty‑nine divisions in the three military regions opposite Taiwan, only twenty‑eight are main‑force divisions, which are likely to be used in such an operation. The remainder are local‑force units which are equipped, trained, and intended primarily for area‑defense operations. 3. The additional thirty or so maneuver divisions projected as being necessary for a successful invasion of Taiwan would have to be drawn from military regions whose main‑force units were not directly committed to the northern threat. Included would be at least part of the central reserve of fourteen main‑force divisions in the Wuhan region. These central reserve divisions are the same ones China would use as reserves in a Sino‑Soviet conflict. Therefore, if the Soviets then launched an attack, China might not have sufficient reinforcements readily…
