Asefi Foreign Ministry spokesman Hamid Reza Asefi said here Sunday Iran set no deadline for Europe's reply to Iran's proposals.

"The crossword puzzle of negotiations (between Iran and the European Union) is filling. The Europe should pay attention that we are at a decision-making stage (according to Paris Accord) and will resume enrichment one day with or without an agreement.

"It will be to the two sides' interest such an issue would end to an agreement," Asefi told domestic and foreign reporters at his weekly press conference.

Asked about news of former Russian energy minister's arrest in Switzerland and its link with Iran's nuclear case, he said, "Iran had quite transparent nuclear cooperation with Russia within the framework of international regulations.

"Iran has not violated terms of Non-Proliferation Treaty in nuclear activities." " Iran insists on its rights enshrined by NPT and our nation will never overlook their rights," Asefi said, stressing the key role of broad cooperation with Europe and the objective guarantees that Iran provided on peaceful nuclear activities.
