United Nations Security Council resolution 658, adopted unanimously on 27 June 1990, after recalling Resolution 621 (1988) and noting a report by the Secretary-General on the situation in Western Sahara, the Council approved the Secretary-General's recommendations regarding a settlement of the issue.
The resolution called upon both parties to co-operate with the Secretary-General and the Organisation of African Unity in their efforts to find a settlement in Western Sahara, welcoming the Secretary-General's decision to send a technical mission to Western Sahara and neighbouring countries to finalise administrative aspects of the United Nations plan. In this regard, it called on the Secretary-General to report back once this had been completed.
