Several countries of the Coordinating Committee for Multilateral Export Controls (CoCom) member nations had illegally exported to the Soviet Union machine tools that could be used in combination with the Kongsbergnumerical control (NC) devices made in Norway in violation of the CoCom agreement during the Cold War.
