The top Spanish senator hailed the positive consequences of the 2015 nuclear accord for Iran-Spain ties. "JCPOA has created a very good opportunity for boosting mutual trade and investment, and we are already witnessing its positive impact on economic relations between Iran and Spain," President of Spanish Senate Pio Garcia Escudero was quoted as saying by IRNA in a meeting with Foreign Minister Mohammad Javad Zarif in Tehran on Sunday. JCPOA stands for the Joint Comprehensive Plan of Action, the official title of the deal that has been in effect since January 2016 to ease sanctions against Iran in return for rolling back its nuclear program. Escudero was in Iran to attend the Saturday inauguration ceremony of President Hassan Rouhani who won a strong mandate in May to lead the executive branch for a second term. The senior lawmaker expressed his side's eagerness to deepen the 'longstanding' bilateral engagement in all domains. Zarif said the Iranian market offers lucrative investment opportunities to European businesses, citing Iran's strategic geographical position, large skilled workforce and stability.
