Foreign relations of Laos
The foreign relations of Laos, internationally designated by its official name as the Lao People's Democratic Republic, after the takeover by the Pathet Lao in December 1975, were characterized by a hostile posture toward the West, with the government of the Lao People's Democratic Republic aligning itself with the Soviet bloc, maintaining close ties with the Soviet Union and depending heavily on the Soviets for most of its foreign assistance. Laos also maintained a "special relationship" with Vietnam and formalized a 1977 treaty of friendship and cooperation that created tensions with China.
