the free movement of people to Croatia, which led to Switzerland's full readmission into Horizon 2020, a European funding framework for research and development. The treaty was ratified by the National Council on 26 April on the condition that a solution be found to an impasse on implementing the 2014 referendum. The treaty was passed in December 2016. This allowed Switzerland to rejoin Horizon 2020 on 1 January 2017. A poll in December 2022 to mark 30 years since the 1992 EEA referendum indicated that 71% would vote for EEA participation if a referendum were held. Support for joining the EU was just 32%. Foreign policy In the field of foreign and security policy, Switzerland and the EU have no overarching agreements. But in its Security Report 2000, the Swiss Federal Council announced the importance of contributing to stability and peace beyond Switzerland's borders and of building an international community of common values. Subsequently, Switzerland started to collaborate in projects of EU's Common Foreign and Security Policy (CFSP). Switzerland has contributed staff or material to EU peace keeping and security missions in Bosnia and Herzegovina, the Democratic Republic of the Congo, Kosovo, North Macedonia and the province of Aceh, Indonesia.

Those affected the former Republic of Yugoslavia (1998), Myanmar (2000), Zimbabwe (2002), Uzbekistan (2006) and Belarus (2006).

Many shops and smaller businesses that accept euros take notes only, and give change in Swiss francs, usually at a less favourable exchange rate than banks. Many bank cash machines issue euros at the traded exchange rate as well as Swiss francs. On 6 September 2011, the Swiss franc effectively became fixed against the euro: the Franc had always floated independently until its rapid currency appreciation during the eurozone debt crisis.
