Non-state factors begin to play more and more significant role in processes of global management. The international non-governmental organizations are on a special place among them (INGO). In the last decade they are growing noticeably. In this regard it is necessary to study the role and the meaning of international non-governmental organizations in the process of global management. It is a vital need of modern science. Attempts to elaborate definition of the concept "international non-governmental organization" were made repeatedly but all developed concepts have certain shortcomings (don't reflect the legal nature of INGO, membership, activity purposes, etc.). The bulk of non-governmental organizations are created for the solution of specific problems or work within a certain perspective. Today these organizations actively deal with issues connected with humanitarian assistance, protection of human rights and environmental protection, providing peace and safety, participate in educational programs, sports projects. They provide analysis and expert assessment of various problems, including global problems, act as mechanism of "early notification" and promote control of international agreements execution. But, without looking, for rather positive role of MNPO in their activity there are also certain problems. INGO is often accused in internal state affairs. Their activity often has politized character.
