Analyzing transformations taking place in the world economy, we can observe an increase in the number of actors participating in the discussion concerning the functioning of the global trade governance. Similar tendencies are noticeable within national economies. In this case, the number of actors participating in the discussion concerning the shape of the trade policy implemented by the state is systematically increasing. Both in Geneva as well as on national forums, numerous industrial associations, business coalitions and multinational corporations are present. NGOs calling for respect for human rights, environmental protection, sustainable development as well as the so-called alter-globalists are also very active in the discussion regarding trade policy issues. Activity of these actors takes two extreme forms: 1) initiating or supporting activities of states; 2) competition or contestation of efforts made by states involving organization of social protest. Non-state actors differ not only concerning their intensity of involvement in trade policy making, but also concerning efficiency of their impact on state within this process, and most of all goals they wish to achieve. The aim of the paper is to analyze role of non-state actors in trade policy-making process, i.e. influence of non-governmental organizations and civil society on trade negotiations and global trade governance.
