Subnational diplomacy can sometimes create tensions with national governments if it contradicts national foreign policy objectives. This is because subnational entities might pursue interests that diverge from the national agenda, leading to conflicts in international relations.

The rise of subnational diplomacy is linked to increasing globalization and decentralization. In the 1980s and 1990s, increased trade and investment flows led subnational entities to recognize the importance of international engagement. The European Union's emphasis on regional development also played a role. Digital technologies have further facilitated subnational diplomacy by enabling easier communication and collaboration across borders.

Cities are playing a growing role in addressing global challenges such as migration and public health. They engage in international networks and collaborations to share best practices and implement solutions at the local level. This helps in complementing national efforts and building resilience in urban areas.

Increased focus on climate change has led to greater subnational engagement in international climate negotiations (2023). Subnational entities are actively participating in these negotiations to advocate for ambitious climate action and share their experiences in implementing climate policies. This helps in accelerating the transition to a low-carbon economy.
