Current Intelligence Staff Study North Vietnam and Sino‑Soviet Relations (Reference Title: ESAU eighteen sixty‑two). Office of Current Intelligence, Central Intelligence Agency. This is a working paper, the third in a series of ESAU studies of components of the world communist movement in the context of the Sino‑Soviet relationship.
