With the dispute over Iran’s controversial nuclear program moving this week to the United Nations Security Council, the stage is set for a perilous confrontation between the Islamic Republic and the international community – a showdown that not only Tehran but also world powers China and Russia have fought to avoid.
While reporting Tehran to the Security Council is being executed in the name of preventing nuclear proliferation, China has voiced fears that the whole non-proliferation system has been destabilized by the freshly inked nuclear deal between the United States and India.
