During the break-up of the Soviet Union, the Republic of Belarus declared its independence on 25 August 1991. Switzerland recognised the new state on 23 December of the same year. Between 1992 and January 2018, the Swiss ambassador to Poland was also cross-accredited in Minsk. On 15 May 2019 the Federal Council decided to upgrade the Swiss representation office, which has represented Switzerland in Minsk since 2010, to a full embassy and to accredit a Swiss ambassador to Belarus with residence in Minsk.
Federal Councillor Ignazio Cassis, head of the Federal Department of Foreign Affairs, made the first working visit of a federal councillor to Minsk in February 2020. He took this visit as the occasion to officially open the embassy. During his stay, Cassis held bilateral talks with President Alexander Lukashenko and Foreign Minister Vladimir Makei.
After diplomatic relations were established between the two countries in 1992, Belarus opened an embassy in Bern which was managed by a chargé d'affaires from 2008 to 2020. In 2020, Belarus appointed an ambassador to Switzerland, who presented his credentials on 1 September 2020.
