Transnational advocacy networks and epistemic communities are linked by:

Transnational advocacy networks (TANs) and epistemic communities are both forms of non-state actors that influence global politics. They are fundamentally linked by their shared characteristics:

• Expertise: Both rely on specialized knowledge and information to frame issues and propose solutions.
• Activism: TANs are explicitly activist groups, while epistemic communities often engage in advocacy to promote their policy-relevant knowledge.

They collaborate on social issues, leveraging their knowledge and collective action. Options like nationalism, geography, educational background, or former government service are not the primary linking factors, as these groups often transcend national borders and draw members from diverse professional backgrounds united by their shared cause and knowledge.
