The head of the United Nations’ nuclear watchdog on Monday renewed calls for Iran to provide “timely and proactive cooperation” in inspections that are part of the deal meant to prevent it from developing nuclear weapons.

Last month, in its first report since the U.S. withdrawal from the 2015 nuclear deal that Israel also opposes, the International Atomic Energy Agency said that Iran continues to stay below the maximum level to which it is allowed to enrich uranium and appears to be fulfilling other obligations. But it said Iran is slow when it comes to “complementary access” inspections.

Amano told the IAEA’s board of governors that “timely and proactive cooperation by Iran in providing such access would facilitate implementation … and enhance confidence.”

At a news conference later Monday, Amano said that his statement was “not an expression of concerns or complaints, but rather an encouragement to Iran.”
