China, Russia, and Iran demanded an end to Washington's "illegal, unilateral sanctions" on Tehran, after three-party talks on the Iranian nuclear issue in Beijing on March 14.
But a leading sanctions expert involved in past nuclear talks with Iran says lifting sanctions as a precursor to negotiations is neither likely nor advisable.
The meeting included Chinese Deputy Foreign Minister Ma Zhaoxu, Russian Deputy Foreign Minister Sergei Ryabkov, and Iranian Deputy Foreign Minister Kazem Gharibabadi.
