Bilateral relations Switzerland–Luxembourg

The relationship between Switzerland and Luxembourg has traditionally been very good and close. It is based on mutual respect and deep trust. The two countries share the same values and have several characteristics in common: a central location in Europe, French and German as official languages, multilingualism, a major financial centre, a high level of innovation, and a pragmatic approach in politics and business.

Key aspects of diplomatic relations

Diplomatic exchanges between Switzerland and Luxembourg focus on several key areas, which reflect the close and excellent relations between the two countries. In addition to the areas of economics and finance, these include, amongst other things, Switzerland’s relations with the EU.

Regular high-level contacts are also held within the framework of the informal meetings of German-speaking ministers and the Six-Nation Meeting of German-speaking heads of state.

The two countries additionally work closely together in international organisations such as the United Nations, the Organisation for Security and Co-operation in Europe and the Council of Europe.

Economic cooperation

Switzerland and Luxembourg maintain close economic ties, which are characterised primarily by the financial and services sectors. While trade in goods plays a relatively minor role due to Luxembourg’s small size, the financial centre is of considerable importance to both countries. During the visit of Luxembourg’s Minister of Finance to Switzerland in May 2026, it was agreed to establish a structured financial dialogue and to collaborate with the University of St Gallen on a joint Finance MBA programme, to start in the 2027/2028 academic year.

Already in January 2024, did Luxembourg join the SDG Impact Finance Initiative (SIFI) – a public-private partnership launched in Switzerland to promote impact-oriented investment. This strategic partnership strengthens the synergies between the two pioneers in the field of sustainable finance.

Cooperation in education, research and innovation

Cooperation between Switzerland and Luxembourg in education and research is characterised by close collaboration and mutual support, fostering innovation, academic excellence and scientific research. These exchanges are facilitated by bilateral agreements between the two countries' universities. Both states also attach great importance to lifelong learning and continuing professional development.

Swiss excellence scholarships will not be awarded in the 2025/2026 academic year due to a lack of reciprocity.

History of bilateral relations

In 1309, Emperor Henry VII, Count of Luxembourg, granted imperial immediacy to the three forest cantons of Uri, Schwyz and Unterwalden. In 1843, Luxembourg joined the German Customs Union and consequently became economically linked to Switzerland. In 1929, Switzerland signed an economic treaty with the Belgium-Luxembourg Economic Union, which had been established by Belgium and Luxembourg in 1921.

The 110th anniversary of diplomatic relations with Luxembourg will be celebrated in 2027, marking the opening of a legation by the Grand Duchy of Luxembourg in Switzerland in November 1917. Up until a Swiss embassy was established in Luxembourg in 1970, the Swiss envoy in Brussels was also accredited to Luxembourg.
