The Organisation of African Unity and the Non-Aligned Movement passed resolutions condemning Zionism and equating it with racism and apartheid during the early 1970s. The United Nations General Assembly passed Resolution 3151 72 to 36, with 32 abstentions, in December 1973, stating that there was an "unholy alliance between South African racism and Zionism."
Resolution 3379 passed in November 1975, supported by Arab, African and Soviet bloc states, declaring that "Zionism is a form of racism."
As the war in Iraq began and the South Africa's apartheid government and the Soviet Union collapsed, the resolution was repealed in 1991 with Resolution 4686, after Israel declared that it would only participate in the Madrid Conference of 1991 if the resolution were revoked.
At the session revoking the motion, U.S. President George H. W. Bush declared that 3379 mocked the founding principles of the United Nations and its charter's pledge "to practice tolerance and live together in peace with one another as good neighbors."
The revocation motion was co-sponsored by 90 nations and supported by 111, and opposed by 26.
