TEHRAN -- Iran will not accept written assurances from the United States as a basis for reopening diplomacy, insisting that Washington must demonstrate its commitment through concrete actions after repeatedly breaking its promises in negotiations, a senior Iranian security official said Friday.
Ali Bagheri, deputy secretary of Iran’s Supreme National Security Council, said Tehran has the right to demand tangible evidence of a change in U.S. conduct before considering a new diplomatic process.
“Over the past year and a half, the Americans have derailed negotiations through their breach of commitments. It is Iran’s right not to settle for America’s paper commitments before entering a new phase of diplomacy,” Bagheri said. 
He stressed that Iran must be able to see Washington’s actions for itself, adding that only after practical steps have been taken could the conditions emerge for opening a new chapter in diplomatic engagement.
“The Islamic Republic must see the practical actions of the United States with its own eyes. Once these actions are observed, the ground can be prepared for opening a new chapter,” he said.
Bagheri’s remarks underscore Tehran’s deepening distrust of Washington following repeated diplomatic breakdowns and military confrontations, as Iran maintains that any future negotiations must be accompanied by verifiable changes in U.S. policy rather than political declarations or written guarantees.
The senior official also discussed a recent visit by the secretary of Iran’s Supreme National Security Council to Moscow, where he held an extensive meeting with Russian President Vladimir Putin.
Bagheri said the meeting lasted approximately three hours and that the principal purpose of the visit was to deliver a message from Leader of the Islamic Revolution Ayatollah Seyyed Mojtaba Khamenei to the Russian president.
The message outlined Iran’s priorities for bilateral cooperation and presented a broader vision for future relations, he said, adding that it was intended to give Moscow a clearer understanding of Tehran’s approach to cooperation under the new leadership.
He identified two major strategic projects — the transfer of Russian natural gas to Iran and the International North-South Transport Corridor (INSTC) — as key instruments for strengthening bilateral ties and reducing external pressure on the country.
“These strategic projects will dispel the illusion held by certain powers, including the United States, that they can pressure the Islamic Republic of Iran,” Bagheri said.
He described the projects as economic assets that could contribute to Iran’s development, promote regional prosperity and strengthen security.
The proposed Russian gas transfers and the INSTC, which is designed to connect Russia and northern Europe with Iran and markets further south, could also expand regional trade and transit connectivity, reinforcing the strategic importance of cooperation between Tehran and Moscow.
