TEHRAN, May 23 (Xinhua) -- Iran's Supreme Leader Ayatollah Ali Khamenei on Wednesday urged the European parties to Iranian 2015 international nuclear deal to guarantee Iran's interests against U.S. pressures, according to the leader's official website.

Over the past years, the Europeans did not protest against the U.S. continuous violation of the nuclear deal, also known as Joint Comprehensive Plan of Action (JCPOA), Khamenei said.

To work with the Europeans over the JCPOA, they should condemn U.S. withdrawal from the nuclear deal, which violates the UN resolution of 2231.

"They (the Europeans) should propose an anti-U.S. resolution to the UN Security Council and protest the U.S. move" of pulling out from the deal, he said.

In the talks with Europe over the salvage of the JCPOA, they should ensure that they will not raise the issues concerning Iran's missile program and its regional role, he pointed out.

Besides, the EU should support Iran against the U.S. new sanctions, and their banks should work with Iran for the financial transactions, he said, adding that they should also ensure that "they will buy Iran's oil as much as we need."

They Iranian leader warned that Iran preserves the right to resume its nuclear activities in case the ongoing talks with Europe over the JCPOA fail.

Iran pushes the EU for the revival of "the blocking statute" which is a 1996 regulation that prohibits EU companies from complying with the U.S. sanctions.

Iran's Foreign Minister Mohammad Javad Zarif said earlier that the political support of the Europeans to the Iranian nuclear deal is "not enough."

"With the exit of the United States from the nuclear agreement, expectations from the EU are high to preserve the achievements of the deal," Zarif said.

"EU should take further practical steps to continue economic cooperation with Iran," he said, adding that "EU should boost investments in Iran."

He expressed doubt that the obligation of Europe to implement the JCPOA is in contradiction with the withdrawal of major European companies from Iran's projects after U.S. pulled out.
