Other communist countries in Eastern Europe also supplied arms and military advisors, including the German Democratic Republic (East Germany).  Support from other African countries was more limited.  Neighboring Zaire and South Africa actively backed the FNLA and UNITA, both committing significant numbers of soldiers to fight the MPLA.  Other African nations were less hostile; during the independence war the organization was based at different times in Congo-Brazzaville, Tanzania, and Zambia.
