The arguments over domestic and military strategy also carried a foreign policy element, as North Vietnam, like South Vietnam, was largely dependent on outside military and economic aid. The vast majority of North Vietnam's military equipment was provided by either the Soviet Union or China. Beijing advocated that North Vietnam conduct a protracted war on the Maoist model, fearing that a conventional conflict might draw China in, as had happened in the Korean War. They also resisted the idea of negotiating with the allies. Moscow, on the other hand, advocated negotiations, but simultaneously armed Hanoi's forces to conduct a conventional war on the Soviet model. North Vietnamese foreign policy therefore consisted of maintaining a critical balance between war policy, internal and external policies, domestic adversaries, and foreign allies with "self-serving agendas."
