Tehran, Jul 29 (IANS): Iran on Monday warned the European signatories of the 2015 Iranian nuclear deal of withdrawing from more of its commitments under the deal if they fail to meet Tehran's demands.

"We are still waiting for the Europeans' practical and concrete measures in implementing the nuclear deal," Iranian Foreign Ministry Spokesman Abbas Mousavi said in his weekly press conference.

"Tehran's patience is running out," Mousavi said, adding that Iran would take "the third step if the Europeans fail to honour their commitments once again".

On Sunday, Abbas Araqchi, Iranian envoy to the nuclear talks, also said that Tehran will continue to abandon more of its commitments pertaining to the deal if the remaining parties to the 2015 accord fail to help Iran reap its economic interests.

Iran has already withdrawn from parts of its obligations under the nuclear deal after the US President Donald Trump pulled Washington out of the pact, better known as the Joint Comprehensive Plan of Action, in May 2018 and re-imposed sanctions against Iran.

To secure trade with Tehran and skirt US anti-Iran sanctions, the European Union announced the launch of its special payment channel with Iran, namely INSTEX, in January.

However, Tehran said that the EU mechanism lacked feasibility in supplying Iran with petrodollars.
