Which non-EU microstate is a neighbour of the country which held an immigration referendum in February 2014?
Switzerland–European Union relations The relations between Switzerland and the European Union (EU) are framed by a series of bilateral treaties whereby the Swiss Confederation has adopted various provisions of European Union law in order to participate in the Union's single market. All but one (the microstate Liechtenstein) of Switzerland's neighbouring countries are EU member states.
Crimean status referendum, 2014 A controversial referendum on the status of Crimea was held on March 16, 2014, by the legislature of the Autonomous Republic of Crimea and by the local government of Sevastopol (both subdivisions of Ukraine). The referendum requested local populations whether they wanted to join Russia as a federal subject, or if they wanted to restore the 1992 Crimean constitution and Crimea's status as a part of Ukraine. As a result of the events of Euromaidan, the referendum was held directly after a Russian military takeover of Crimea. Because of this, the referendum's legitimacy has been heavily disputed by the international community.
