The interests, structure, and influence of NSAs vary widely. For example, among NSAs are corporations, media organizations, business magnates, people's liberation movements, lobby groups, religious groups, aid agencies, and violent non-state actors such as paramilitary forces.
Some common and influential classes of NSAs are listed here in alphabetical order:
- Business magnates are individuals who command large wealth, and who often seek to influence national and international affairs. Examples are Warren Buffett and Bill Gates.
- Corporations, which include multinational corporations (MNCs), are companies authorized to act as single entities (legally as persons) and are recognized as such in law. They include very large businesses operating transnationally, such as The Coca-Cola Company.
- Decentralized autonomous organizations (DAO)s, sometimes known as decentralized autonomous corporations (DACs), operate according to rules encoded as computer programs called smart contracts.:229 The crypto-currency Bitcoin is an example of a DAO which, as of 2018, has grown to become economically influential.
- International media agencies, which are also usually corporations, report on the social and political situation in countries worldwide, and may therefore be highly influential as NSAs. Agence France-Presse is an example.
- Non-governmental organizations (NGOs), which include international non-governmental organizations (INGOs), are usually nonprofit organizations seeking to effect change in humanitarian, educational, ecological, healthcare, public policy, social, human rights, environmental, and other areas. An example is Greenpeace. Goodwill ambassadors or humanitarian aid workers involved with INGO missions abroad may also be considered as non-state actors.
- People's movements are mass movements which become influential with size and longevity. Examples include the movements arising during the Arab Spring of 2011.
- Religious groups commonly engage in political affairs at an international level. For example, the Quakers, as an historic peace church, operate offices at the United Nations. Another example is ISIS, which is a religious group as well as a violent non-state actor.
- Transnational diaspora communities are ethnic or national communities that commonly seek to bring social and political change to their originating countries and their adoptive countries. The Israeli diaspora is an example.
- Unincorporated associations, secret societies and civic organizations unknown to or unrecognized by the state or government may be considered non-state actors.
- Unrepresented nations and peoples include many indigenous peoples and Fourth World societies.
- Violent non-state actors (VNSA)s are armed groups, including groups such as ISIS or criminal organizations, for example drug cartels.
- World citizens may be considered non-state actors if they are active in movements or social causes active outside their own country.
Effects on the Westphalian state model
The proliferation of non-state actors in the post–Cold War era has been one of the factors leading to the Cobweb Paradigm in international politics. Under this paradigm, the traditional Westphalian nation-state experiences an erosion of power and sovereignty, and non-state actors are part of the cause. Facilitated by globalization, NSAs challenge nation-state borders and sovereignty claims. MNCs are not always sympathetic to national interests, but instead are loyal to the corporation's interests. NSAs challenge the nation-state's sovereignty over internal matters through advocacy for societal issues, e.g. human rights and the environment.
Armed non-state actors operate without state control and are involved in internal and trans-border conflicts. The activity of such groups in armed conflicts adds layers of complexity to traditional conflict management and resolution. These conflicts are often fought not only between non-state actors and states, but also between multiple NSA groups. Interventions in such conflicts is particularly challenging given the fact that international law and norms governing the use of force for intervention or peacekeeping purposes was primarily written in the context of the nation-state.
Example: Cotonou Agreement
The term Non State Actors is widely used in development cooperation, particularly under the Cotonou Agreement between the European Union (EU) and African, Caribbean and Pacific ACP countries. The agreement uses the term to refer to a wide range of nongovernmental development actors whose participation in ACP-EU development cooperation is now formally recognized. According to Article 6, non-state actors include:
- civil society in all its diversity, according to national characteristics;
- economic and social partners, including trade union organisations and;
- the private sector.
In practice, it means that participation is open to all kind of actors, such as community-based organisations, women's groups, human rights associations, non-governmental organisations (NGOs), religious organizations, farmers' cooperatives, trade unions, universities and research institutes, the media and the private sector. Also included in this definition are informal groups such as grassroots organizations, informal private sector associations, etc. The private sector, however, is considered only insofar as it is involved in non-profit activities (e.g. private sector associations, chambers of commerce, etc.)
Non-state actors can aid in opinion building in international affairs, such as the Human Rights Council. Formal international organizations may also rely on non-state actors, particularly NGOs in the form of implementing partners in the national context. An example is the contribution of COHRE (Centre on Housing Rights and Evictions), to the protection of land and property (HLP) rights in Kosovo by conceptualizing the Housing and Property Directorate (now Kosovo Property Agency) within the framework of the United Nations Interim Administration Mission in Kosovo.
Non-state actors are fundamental agents in helping to achieve both national and international development goals, such as those around climate change. Actions by non-state actors contribute significantly towards filling the greenhouse gas emissions gap left by unambitious or poorly executed national climate policies, Intended Nationally Determined Contributions (INDCs).
Another example that shows the importance of non-state actors in peace-building is the contribution of ICBL (International Campaign to Ban Landmines) to the international prohibition on the use of landmines. ICBL is a global network of NGOs that has operated in over 90 countries since 1992. Its primary goal is to make a world free of anti-personnel landmines. Their passionate advertising appealing for global cooperation drew Diana, Princess of Wales to become an ardent advocate. Together, they brought the issue to the United Nations General Assembly. ICBL's efforts led the international community to urge states to ratify the Ottawa Treaty (Mine Ban Treaty) in 1997, and its contribution was recognized and praised as it was awarded the Nobel Peace Prize in the same year.
