The International Atomic Energy Agency (IAEA) chief Rafael Grossi is expected to visit Tehran on Saturday to talk about a solution for the IAEA to continue essential verification activities in the country. Iran announced earlier this week it would stop on February 23 implementing voluntary transparency measures under the 2015 nuclear deal, which would impact IAEA's monitoring activities. Chinese Foreign Minister spokesperson Hua Chunying said on Thursday China supports the IAEA and Iran in properly handling issues related to safeguards through dialogue and consultation, hoping that all parties will play a constructive role in this regard. She also called on the U.S. to return to the nuclear agreement.
