In relevant remarks in December, Iranian Chargé d'Affaires to Switzerland Mehdi Abedi voiced his optimism about the prospects of trade relations between Iran and Switzerland, saying that the two countries' economic ties are entering a new phase of cooperation.

"The expansion of ties with Switzerland is important as the country is regarded as one of the world's most important financial and economic center," Abedi said.

He reiterated that after the implementation of the JCPOA, Switzerland also removed sanctions on Iran and new movements were started in different economic fields like last year's visit of the Swiss president to Iran during which both sides agreed on drawing a road map of all-out ties.
