1. I am citing official UN documents, not Western media accounts.
2. As I mentioned earlier, this event is still in the diplomatic confrontation stage. Its development is unpredictable and could change at any time. The joint letter from China, Russia, and Iran to the UN that you mentioned occurred on October 19, 2025, representing a new development. A more recent development is that on October 30, 2025, Geng Shuang, China's Deputy Permanent Representative to the UN, reiterated at the UN General Assembly reviewing the IAEA's annual report that Resolution 2231 had expired and terminated... He also reiterated his criticism of the US-UK-Australia nuclear submarine cooperation... These are all diplomatic maneuvers. They are still a long way from becoming a reality.
3. As I emphasized earlier, China and Russia have been working to have the UN lift sanctions against Iran. This is the official stance of the Chinese government. In other words, we are currently still acting within the framework of the UN.
China, Russia, and Iran's accusation that the E3's initiation of the "snapback" sanctions mechanism is legally flawed and lacks legal basis, and therefore invalid. ------ This is still a diplomatic confrontation within the framework of UN rules of procedure.
