TEHRAN, Iran – Iran is ready to show flexibility at nuclear talks to ease Western concerns over its contentious nuclear program, its foreign ministry spokesman said on Saturday, as tensions rise in the standoff between the Islamic republic, Israel and the West.

The remarks by Ramin Mehmanparast, published by the official IRNA news agency, underscore Tehran’s push to resume talks with world powers as Western sanctions squeeze the economy tighter and the European Union weighs a boycott of Iranian natural gas.

“Iran is ready to show flexibility to remove concerns within a legal framework but such measures should be reciprocal,” Mehmanparast said. “The other party needs to take measures to fully recognize Iran’s nuclear rights and Iran’s enrichment for peaceful purposes.”

The five members of the U.N. Security Council, plus Germany and Iran, aim to resume high-level talks that were suspended in June. The countries want the Islamic republic to stop enriching uranium to 20 percent purity because at that level the material can be quickly turned into fuel for nuclear weapons.

Iran has indicated it is ready to stop the higher enrichment if sanctions are lifted and its right to enrich is recognized. The U.S. and its allies accuse Iran of seeking to develop a nuclear weapon, a charge Tehran denies.

Western powers are pursuing a two-pronged strategy that includes a mix of sanctions and diplomacy to try to force Tehran to halt uranium enrichment, a technology that can be used to produce nuclear fuel or materials for use in a warhead.
