Lavrov Takes Russia’s Mediation Bid From Manama to Tehran

TEHRAN, 19 October 2026 – Russian Foreign Minister Sergey Lavrov arrived in Tehran on Monday for his first visit to Iran since US and Israeli strikes opened the war on 28 February. He came directly from Manama, where on Sunday he met Gulf Arab ministers. Russian news agencies reported his arrival, according to Arab News (AFP). Lavrov said the trip was “aimed at preventing the return of a large-scale war.”

Taken together, the two stops show what Moscow is offering as a mediator: what it says in Gulf Arab capitals, what it has signed with Tehran, and what Washington has said about Russia’s role. Our Iran War Tracker follows the wider conflict.

What Lavrov said in Manama

On 18 October, Lavrov attended the ninth ministerial meeting of the Russia–Gulf Cooperation Council (GCC) Strategic Dialogue in Bahrain, a format he said was marking its fifteenth year. The Russian Foreign Ministry published the transcript of his news conference in Russian. The quotations below are Peter’s World translations.

Asked about attacks on Gulf states and shipping, Lavrov said he endorsed “fully and without reservation” a return to freedom of navigation “as it existed before 28 February,” adding: “Before 28 February the freedom was complete, without a hint of any payments.” AFP reports that Iran claims control of the Strait of Hormuz and regularly targets vessels that cross without its authorisation.

On diplomacy, he pointed to the US–Iran memorandum, which he called the “Islamabad memorandum.” He said the memorandum “still contains everything needed” to move the situation “from its current stage, when it is balancing on the brink of a resumption of full-scale war,” back to negotiations.

He also proposed a regional security forum. It would bring together the Arab Gulf states, Iran and neighbours such as Iraq and Jordan, and would draw on Russia’s long-standing Collective Security Concept for the Persian Gulf as well as GCC, Chinese and Iranian proposals. Lavrov said Russia’s trade with the six GCC states rose 45% last year to almost $19 billion.

On the sidelines, Lavrov met Saudi Foreign Minister Faisal bin Farhan. A Russian Foreign Ministry readout said both sides expressed concern over “the tension in the south of the Arabian Peninsula and in the Bab-el-Mandeb Strait,” where Saudi Arabia and the Iran-backed Houthis are trading strikes.

The agenda for Lavrov in Tehran

The ministry’s announcement of the visit said Lavrov would be received by President Masoud Pezeshkian and hold talks with Foreign Minister Abbas Araghchi. It described the meeting as the ministers’ fourth in person this year, alongside 14 phone calls. The agenda covers the Gulf crisis, which the ministry blamed on “unlawful aggression” by the United States and Israel. It also includes follow-up on Putin–Pezeshkian meetings in Bishkek on 1 September and Avaza on 8 October, plus transport, logistics and energy projects. President Vladimir Putin told Pezeshkian in early October that Moscow was prepared to contribute to mediation efforts, according to AFP. No outcome from Monday’s talks had been announced at the time of publication.

The visit comes as Tehran keeps its seven-day ceasefire plan on the table. In comments carried by CBS News, Araghchi said that if the United States meets Iran’s conditions, which include lifting the naval blockade, “the Strait of Hormuz will reopen on the sixth day, and negotiations will begin on the seventh day.”

How Russia and Iran got here: a timeline

• 12 March 2001: Russia and Iran sign the Treaty on the Basis for Mutual Relations and Principles of Cooperation, which the 2025 treaty cites as a foundation.
• 15 November 2022: The US Treasury sanctions Shahed Aviation Industries, saying Iranian drones were being used by Russian forces in Ukraine (Treasury).
• 10 September 2024: Treasury says Russia received its first shipment of Iranian close-range ballistic missiles in early September 2024, after Russian personnel were trained on them that summer (Treasury).
• 17 January 2025: Putin and Pezeshkian sign the Treaty on Comprehensive Strategic Partnership in Moscow. It enters into force on 2 October 2025, according to Lavrov.
• 28 February 2026: US and Israeli strikes on Iran begin the current war.
• 18 June 2026: The United States and Iran sign a memorandum on ending the war, according to Xinhua.
• 24 September 2026: Lavrov and Araghchi meet at the UN General Assembly in New York.
• 16 October 2026: President Trump waives some Russia sanctions and duties under the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, days before they were to take effect, according to Iran International and CBS News.
• 18–19 October 2026: Lavrov visits Manama, then Tehran.

What the 2025 treaty does, and does not, commit Russia to do

The treaty text is published on the Iranian presidency’s website. Its security articles are narrower than a defence pact.

Nikita Smagin of the Carnegie Endowment noted that Russia’s 2024 pact with North Korea includes a mutual assistance clause, and that the security provisions of the Iran treaty are “almost identical” to those of the 2001 treaty.

Washington’s view of Russia’s role

Trump wrote on 18 October that “Russia is doing very little, if anything, to help the Islamic Republic of Iran, compared to what they could be doing, and I want to keep it that way,” USA Today reported. He linked that statement to the sanctions waiver, saying he did not want to drive Russia “away from the bargaining table” on Ukraine. Asked in Manama about a separate US–Russia diesel arrangement, Lavrov said it “concerns Moscow and Washington” alone.

Analysis: what Russia can and cannot offer

Peter’s World analysis, based on the sources cited above.

Moscow’s pitch has two audiences, and the Manama transcript shows how it balances them. To Gulf Arab states, his call for passage without payments matched the stress on unhindered navigation in the Russian readouts of his Saudi and Bahraini meetings, and it runs against Iran’s claim to authorise traffic through the strait. To Tehran, the ministry’s framing puts the blame on Washington and Israel, and it offers the June memorandum as the basis for a return to talks rather than a new negotiation.

The treaty sets the limits of the offer. Article 3 commits Russia only to not helping an attacker. It does not commit Russia to defending Iran. That leaves Moscow room to keep close ties with Tehran, cooperate with Riyadh in OPEC+ and negotiate sanctions relief with Washington at the same time. The US Treasury record shows that weapons have moved from Iran to Russia for use in Ukraine. Trump’s own words describe Russia’s current help to Iran as limited and say he wants to keep it that way.

Russia’s leverage as a mediator is therefore its access to every party, not its military commitments. Whether that access produces anything may depend on whether Washington accepts a role for Moscow at all.

What to watch: any joint statement or news conference after the Araghchi talks; whether Tehran or Washington publicly accepts a Russian role; Iran’s reply to the US comments on its seven-day plan; and the Gas Exporting Countries Forum summit in Moscow on 25–27 October, which Lavrov said Gulf leaders have been invited to attend.
