Iran may be holding back from working with a U.N. investigation into its nuclear program to use it as a bargaining chip in pursuit of significant sanctions relief or other concessions in broader negotiations with world powers.
That could explain why United Nations nuclear inspectors once again returned empty-handed after talks last week in Tehran, where they tried to overcome obstacles to a long-stalled inquiry into suspected atomic bomb research by Iran.
Iran has suggested at various times in the past that it would expect a “kind of reward” for cooperating with the International Atomic Energy Agency (IAEA), a Western official said, making clear he saw no rationale for this.
If this is Tehran’s thinking, a year-long effort by the IAEA to unblock its investigation looks unlikely to succeed as long as separate diplomacy between the six major powers and Tehran remains deadlocked.
