Tehran is ready for agreement on reviving the 2015 nuclear deal, assuming the United States can be realistic, Iran’s foreign minister said Tuesday.

Hossein Amir-Abdollahian reiterated Iran’s position as he discussed with Chinese counterpart Wang Yi the Vienna nuclear talks aimed at reviving the JCPOA (Joint Comprehensive Plan of Action).

“If the American side is realistic, we will finalize a good, strong, and lasting agreement with the support of all negotiating parties in Vienna,” Amir-Abdollahian said. The foreign minister said the recent pause in the 11-month negotiations between Iran and six world powers could “pave the way for the resolution of issues and the return of all parties to their nuclear deal commitments.”

Wang said China was “willing to strengthen coordination and cooperation with Iran to push the settlement of the Iranian nuclear issue in a direction conducive to regional peace and stability.”

Amir-Abdollahian and Russia foreign minister Sergei Lavrov presented a united front at a Moscow news conference Tuesday over the long-running talks. On Tuesday, an US official was cited by Reuters as accepting a request announced by Lavrov March 5 that any sanctions against Russia over the Ukraine crisis would not affect implementation of a revived JCPOA. Lavrov said Tuesday Moscow had received the assurances it wanted.
