On 21 October 2015 the Federal Council of Switzerland announced that it would also ease its sanctions measures on Implementation Day, in line with the UN and the EU.
The Federal Council declared that it welcomed the formal adoption of the JCPOA on 18 October 2015 and the publication of EU and US legislation needed to lift nuclear-related economic and financial sanctions against Iran, noting that this further easing of sanctions would open new prospects for cooperation with Iran.
For its part, the Swiss Federal Department of Economic Affairs, Education and Research ("EAER") was instructed to prepare the necessary modifications to the Ordonnance on Measures Against the Islamic Republic of Iran (RS 922.214.171.124). Swiss sanctions currently in place against Iran will remain in place until Implementation Day.
