Switzerland's contribution to the enlarged EU
From 2007 to 2024, Switzerland supported various projects in 13 EU countries with a total of CHF 1.302 billion as part of the enlargement contribution, with the aim of reducing economic and social disparities in the enlarged EU.

Starting in 2007, Switzerland contributed CHF 1.302 billion to numerous projects to reduce the economic and social disparities within the enlarged EU. The partner countries of the Swiss enlargement contribution were the EU-13: Bulgaria, Croatia, Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Romania, Slovakia, and Slovenia.
All projects under the enlargement contribution for the EU-10 (those countries that joined the EU in 2004) were successfully completed by the end of 2017 following a ten-year planning and implementation phase. An independent evaluation published in 2016 confirmed that the vast majority of the projects achieved their objectives, in some cases even exceeding the expected results. The projects have made a positive contribution to promoting social and economic development in the partner countries and have made a lasting impact. In Bulgaria and Romania, the implementation phase ended in December 2019. The enlargement contribution in Croatia ran until the end of 2024.
