Interreg is a series of EU funding programmes that support cooperation. By bringing together organisations from across Europe and beyond, Interreg tackles shared challenges and creates lasting connections. From boosting economic growth and regional cohesion to protecting the environment and promoting sustainable development, Interreg-funded projects make a real difference in people’s lives. Together, we are building a more united, resilient and prosperous Europe where every region thrives.

How Interreg strengthens eastern EU regions after Russia’s invasion of Ukraine

Cooperation across borders was once part of daily life for communities along the EU’s eastern border. Regions in Finland, Estonia, Latvia, Lithuania, and Poland had long-standing ties with their Russian and Belarusian neighbours through trade, tourism, and cultural exchanges, supported by Interreg-funded projects. However, Russia’s full-scale invasion of Ukraine in February 2022 abruptly ended these connections. Borders closed, cooperation ceased, and communities faced an uncertain future.
