Iranian Foreign Minister Hossein Amirabdollahian said the onus is on the United States to make the necessary decisions in order to resolve the few outstanding issues in the Vienna talks on the revival of the 2015 nuclear deal, Tasnim reported.

In a telephone conversation on Saturday, Amirabdollahian and his Belgian counterpart Sophie Wilmes talked about issues of mutual interest, with both urging efforts to strengthen the economic and trade ties between Tehran and Brussels.

Highlighting the significance of Iran’s relations with Belgium in terms of bilateral ties and the presence of European and international institutions in the European country, Amirabdollahian described the good ties between Tehran and Brussels that are based on mutual respect as positive.

Pointing to the Vienna talks between Iran and the P4+1 group and the progress made in the negotiations, he underscored that the settlement of a couple of remaining issues requires a decision by the United States.

Amirabdollahian said that the issue is being pursued by the EU’s representative, the Foreign Ministry’s website reported.

For her part, the Belgian foreign minister highlighted the parliamentary cooperation and some agreements between Belgium and Iran.

Wilmes also described the close bilateral cooperation between the two nations as vital for the development of economic ties and resolution of some existing issues.

Iran and the remaining participants to the Joint Comprehensive Plan of Action (JCPOA) have been holding talks in Vienna since April last year with the aim of reviving the deal by bringing the US into full compliance.
