The UN Security Council (UNSC) has endorsed yet another round of sanctions on Iran - the fourth since 2006.

The US and  its allies' claim Iran is secretly trying to develop nuclear weapons is denied by Tehran which insists it has every right to practice a peaceful nuclear programme

The resolution needed the approval of the five veto-wielding permanent members of the UNSC.

This meant getting the approval of China and Russia who have strong economic ties with Tehran.

With both Russia and China finally falling into line, will these sanctions be any more effective than those in the past? And can they help resolve the diplomatic gridlock?

Joining the programme are Justin Logan, associate director of  foreign policy studies at the Cato Institute, Seyed Mohammad Marandi, the head of North American Studies at the University of Tehran, and Anoushka Kurkjian, an independent Middle East analyst.
