Non-state actors have become increasingly important in contemporary international relations. Here are some key roles that they play:

• NGOs: Non-governmental organizations (NGOs) play a critical role in advocating for issues like human rights, environmental protection, and humanitarian aid. They provide a platform for marginalized groups to voice their concerns and often work alongside state actors to achieve their objectives.
• Corporations: Multinational corporations have significant economic power and often operate across multiple countries, which gives them significant influence on international trade and investment. They also have the potential to impact politics and governance in the countries where they operate.
• Terrorist organizations: While their actions are often condemned, terrorist organizations have become increasingly influential in international relations. They use violence and fear to achieve their objectives and can destabilize governments and regions.
• Media: The media is increasingly playing a role in shaping public opinion around international events. Social media has made it easier for individuals to share information and opinions, bypassing traditional gatekeepers of news and information.
• International organizations: Organizations like the United Nations, World Trade Organization, and World Health Organization can also be considered non-state actors. They play an important role in promoting international cooperation and providing a platform for states to work together on issues of common interest.

Non-state actors are not limited to the examples provided above and can include any group or organization that operates outside of formal government structures. Their role in international relations is not always positive, but their impact cannot be ignored.
