Switzerland’s contribution to the enlarged EU

When it joined the EU, Slovenia became one of the countries to benefit from Switzerland’s contribution to reducing economic and social disparities in an enlarged EU. Between 2007 and 2017, Switzerland contributed CHF 20.9 million to the successful implementation of 8 projects in Slovenia based on the Swiss-Slovenian framework agreement of 20 December 2007.

The implementation of the programme was monitored by the Swiss embassy in Ljubljana. The State Secretariat for Economic Affairs and the Swiss Agency for Development and Cooperation in Bern were in charge of approving the projects.

Under the second Swiss contribution, CHF 16 million should be earmarked for projects promoting energy efficiency and renewable energies in Slovenia's alpine region.

Diplomatic relations were established between Switzerland and Slovenia in 1992. Slovenia opened an embassy in Bern in January of that year, while Switzerland established an embassy in Ljubljana in 2001.

During the transitional phase in the 1990s, Switzerland gave its support to a project for the modernisation of the Slovenian administration, leading to the founding of the National Administrative Academy to train Slovenian experts.
