Since 1 January 2017, Swiss researchers and institutions are able to participate in all parts of Horizon 2020.
Switzerland ratified the protocol extending the free movement of persons to Croatia on 16 December 2016. As a result, Switzerland can participate in Horizon 2020 as a fully Associated Country.
The negotiations with the European Union on the association of Switzerland to Horizon 2020 had been suspended following the adoption of the popular vote against mass immigration on 9 February 2014. Meanwhile, an agreement with the European Commission (EC) providing a partial and provisory association to Horizon 2020 had been found. The agreement offered companies, researchers and institutions in Switzerland access to priorities 'Excellent Science' and 'Spreading Excellence and Widening Participation' as well as to activities falling under EURATOM and International Thermonuclear Experimental Reactor (ITER) until the end of 2016.
The condition to be fully associated to Horizon 2020 as of 1 January 2017 was the ratification of the protocol extending the free movement of persons to Croatia. With this condition fulfilled, Swiss researchers and institutions can since 1 January 2017 participate in all parts of Horizon 2020, under the same conditions as Member States of the EU and other Associated Countries.
