In a referendum in February 2014, the Swiss people narrowly approved a proposal to restrict the free movement of foreign nationals in Switzerland. The European Commission said it needed to look at the impact of the result on EU-Switzerland relations, given that the literal implementation referred to the guillotine clause.  For their part, WTO rules do not guarantee Switzerland preferential or duty-free access to the EU market, but mainly serve as a basis for trade relations. The two countries will endeavour to carry out trade between countries on the basis of identical tonnages. The competent authorities of both countries may consult each other in order to implement appropriate measures. Switzerland has extended bilateral treaties to the new EU Member States; each extension honours the approval of Swiss voters in a referendum. The two governments, which recognize the need to impose reciprocal requirements on developing countries, undertake to explore all possibilities for expanding and promoting trade between the two countries on the basis of mutual benefit. If bilateral agreements were denounced, no WTO agreement could act in its place. In 2009, Switzerland became a participant in the Schengen area with the adoption of an Association Agreement by referendum in 2005.  This means that there is no passport control at Switzerland`s borders with its neighbours, although customs controls remain in force.
Switzerland is a member of the European Free Trade Association (EFTA) and participated in the negotiations of the Agreement on the European Economic Area (EEA) with the European Union. It signed the agreement on 2 May 1992 and applied for EU membership on 20 May 1992. However, following a Swiss referendum on 6 December 1992, the Swiss government rejected EEA membership by 50.3% to 49.7% and decided to suspend negotiations on EU membership until further notice. These were not taken up and, in 2016, Switzerland formally withdrew its application for EU membership.   The Free Trade Agreement between Iceland and China entered into force on 1 July 2014. In order to meet the daily needs of persons living in a sixteen-kilometre border belt between West Bengal, Assam, Meghalaya, Tripura and Mizoram, on the one hand, and Bangladesh, on the other, and in order to enable such persons to dispose of their goods, border trade in certain products shall be authorised in accordance with Annex B to the Annex to this Agreement. The seven agreements are closely linked by the obligation to enter into force simultaneously and, at the same time, six months after receipt of a notification of non-renewal or denunciation concerning one of them.  Switzerland participated in the negotiations of the EEA Agreement with the EU, signed the Agreement on 2 May 1992 and submitted an application for membership of the European Union on 20 May 1992. . . .
