Russian Foreign Ministry Spokeswoman Maria Zakharova stated that the meeting is being convened at Germany's request. The source of this claim is the official Russian statement, though independent verification of the specific request is limited to the official's remark.

In an interview with Al Jazeera, the Iranian president stated that Qatar and Pakistan are currently transmitting Tehran's messages to the United States. As this is a single-source assertion, the extent of these diplomatic channels remains unverified by independent observers.

US President Donald Trump and Chinese President Xi Jinping reportedly held discussions on several international issues, including situations involving Russia, North Korea, and Iran. However, the specific details of these talks remain unconfirmed.

US State Department Spokesman Tommy Pigott stated that President Donald Trump holds significant leverage in negotiations with Tehran, according to remarks attributed to the official. These comments reflect the administration's assessment of its negotiating position, though the specific extent of this leverage remains a matter of strategic interpretation rather than a verifiable factual constant.
