Mr Cassis and Ms Monauni paid tribute to the friendly relations between Switzerland and the Principality of Liechtenstein, which are characterised by a close relationship based on mutual trust and numerous joint agreements. They also signed the amendment to the agreement on environmental levies in the presence of both delegations. The agreement regulates cooperation between the two countries in implementing climate policy instruments, including the CO2 targets for vehicles and reduction commitments. The amendment is based on the Federal Council's decision of 2 April 2025 to bring the revised CO2 Ordinance into force and to amend the agreement between Switzerland and Liechtenstein regarding environmental levies in Liechtenstein.

Another key topic on the agenda was bilateral cooperation under the EU Strategy for the Alpine Region (EUSALP), which Liechtenstein is co-chairing with Austria in 2025. The aim of EUSALP is to bolster cooperation between Alpine nations and regions.

Mr Cassis also informed his counterpart about the new package of Swiss–EU agreements, with which the Federal Council intends to stabilise and advance bilateral relations with the EU. Both foreign ministers emphasised the two countries' close cooperation under the European Free Trade Association (EFTA) and in the context of Liechtenstein's role as member of the European Economic Area (EEA).

Security policy developments in Europe were also discussed, with Mr Cassis reaffirming Switzerland's intention to actively promote peace and security in Europe during its OSCE chairpersonship in 2026.

Two centennial anniversaries marking Switzerland and Liechtenstein's close ties were recently celebrated: the Customs Union (2023) and the introduction of the Swiss franc in Liechtenstein (2024). Switzerland has also represented Liechtenstein's interests abroad since 1919.
