The role of multinational enterprises (MNEs) in world trade has continued to increase dramatically since the adoption of these Guidelines in 1995. This in part reflects the increased pace of integration of national economies and technological progress, particularly in the area of communications. The growth of MNEs presents increasingly complex taxation issues for both tax administrations and the MNEs themselves since separate country rules for the taxation of MNEs cannot be viewed in isolation but must be addressed in a broad international context.
