A senior Iranian nuclear negotiator says Europe needs to bear the cost of standing up to US sanctions and other pressure tactics in order to keep the 2015 nuclear agreement with Tehran alive following Washington’s unilateral pullout.

Deputy Foreign Minister Abbas Araqchi pointed to the ongoing efforts by Tehran’s partners to save the deal and said, “That Europeans stand against the US politically and for Iran’s sake would not come about at a low price.”

He admitted, though, that given the US saber rattling, it will not be an easy task for Europeans to find practical mechanisms for meeting Iran’s conditions and keeping the country in the deal.

US President Donald Trump pulled his country out of the Iran deal despite objections from the other signatories, re-imposing the anti-Iran sanctions which were lifted under the agreement, called the Joint Comprehensive Plan of Action (JCPOA).

Washington has threatened punitive measures against European firms doing business with Tehran should they fail to leave the Iranian market in compliance with its bans.

Tehran has said it will stay in the deal only if it is provided with “practical guarantees” that its economic dividends of the deal will remain intact.

In turn, the European signatories have pledged to attempt to protect their business links with Iran in the face of US pressure.

They are now working to finalize an economic package to meet Iran’s conditions for remaining in the JCPOA.

Araqchi further warned that the Islamic Republic would withdraw from the nuclear deal if the Europeans fail by November 4 to design a mechanism to safeguard Iran’s main interests in the accord, including oil sales and banking payments. That is the date when the second round of US sanctions against Iran will snap back.

If the European states fail to put these mechanisms in action until that time, “it is natural that remaining in the JCPOA would be fruitless,” the official stated.

“They are aware that should they fail to provide guarantees and find a solution, we will not remain in the JCPOA,” he added, it only makes sense for Iran to stay in the deal as long as it can continue selling its oil.

He also echoed recent remarks by Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei that Iran will leave the nuclear accord if it fails to serve its interests.

“The JCPOA has economic, political and international benefits for us and we would remain in it until these interests are preserved,” the Leader pointed out.

Iran has lodged a complaint with the International Court of Justice (ICJ) over Washington's move to re-impose the sanctions.
