Although myriad bureaucracies were involved in the formation and execution of Soviet foreign policy, the major policy guidelines were determined by the Politburo of the Communist Party. The foremost objectives of Soviet foreign policy had been the maintenance and enhancement of national security and the maintenance of hegemony over Eastern Europe. Relations with the United States and Western Europe were also of major concern to Soviet foreign policy makers and, much as with the United States, relations with individual Third World states were at least partly determined by the proximity of each state to the border and to estimates of strategic significance.
