Diplomatic relations between Germany and Slovenia were established on 15 January 1992. The two countries enjoy very good relations based on mutual trust. On 1 July 2022, Foreign Minister Baerbock and Slovenian Foreign Minister Fajon signed a joint action plan to intensify bilateral cooperation for the period 2022‑2024; this plan was a success and is set to be continued in the period 2024‑2026.

Bilateral economic cooperation is extremely close. Germany is Slovenia’s second most important trading partner behind Switzerland, accounting for 14.4 percent of the country’s foreign trade. It is also one of the principal foreign investors in Slovenia.

A cultural agreement between Germany and Slovenia has been in force since 1993. With its politically ambitious programming and successful language courses, the Goethe-Institut that opened in Ljubljana in 2004 is an important part of the cultural scene. The German Academic Exchange Service (DAAD) has a lector in the country. Slovenia was the guest of honour at the Frankfurt Book Fair in October 2023.

At 23 Slovenian schools, students can obtain the German Language Certificate (DSD) offered by the Standing Conference of the Ministers of Education and Cultural Affairs. They are supported by an advisor from the Central Agency for Schools Abroad (ZfA) and a number of seconded teachers, as well as by volunteers from the programme “kulturweit”. In total, some 70,000 pupils are learning German. It is the most frequently taught foreign language after English.
