Russian envoy in Iran nuclear talks Mikhail Ulyanov has said that in his meeting with a visiting Israeli delegation in Vienna there was no discussion over Iran.

In an interview with Iran International TV, Ulyanov said that the two sides “disagree on the JCPOA, so there was nothing to discuss” about the Iran nuclear talks.

The Russian envoy, who has taken an active role in the Vienna negotiations, said “We discussed the UN Conference on WMD-Free Zone in the Middle East, where all other regional states participate, except for Israel.” He added, “We maintain regular dialogue with Israeli counterparts.”

The Israeli delegation, headed by Joshua Zarka, the foreign ministry’s deputy director general for strategic affairs, met Tuesday with Ulyanov, Russia’s top negotiator in the Vienna talks, and Monday with Rafael Grossi, director-general of the International Atomic Energy Agency (IAEA).

The visit by the Israeli delegation was seen as an attempt to gauge the state of the talks as diplomats insist the process in its final and critical stage. The United States has warned that time is running out if an agreement is not reached soon.

Israel opposes the revival of the JCPOA, which it believes would be insufficient to stop Tehran from acquiring nuclear weapons and would result in the removal of US sanctions, giving Iran a financial lifeline.
