A nuclear swap deal with Iran, proposed by Turkey and Brazil, is set to come under scrutiny in Vienna.

Tehran is expected to send a letter to the UN nuclear watchdog answering questions over the proposal.

Turkey and Brazil are starting to play a more important and more independent role in international politics, pointed out Igor Khokhlov, fellow with the Institute of World Economy and International Relations in Moscow.

“The Turks have much to offer and contribute to the solution of the problem,” he said.

“The basic idea is to lure Iranians back to the negotiation table,” Khokhlov stated.

Russia, which has always had close relations with Iran, has constantly been realistic and consistent. That is why “Russia does follow international law and Russia also follows its national interests.”
