Russian President Vladimir Putin had a “substantial” phone call with French President Emmanuel Macron on the Iran-Israel conflict and Ukraine, the Kremlin said on Tuesday, the first such exchange between the two leaders since September 2022.

In Paris, Macron’s office said the call lasted two hours and that the French leader had called for a ceasefire in Ukraine and the start of negotiations on ending the conflict.

A French diplomatic source said Macron had talked to Ukrainian President Volodymyr Zelenskiy before and after his call with Putin to brief him on the talks. Macron also talked to US President Donald Trump about the exchange.

According to the Kremlin press service, Putin said it was necessary to respect Iran’s right to the peaceful development of nuclear energy as well as its continued compliance with its obligations under the nuclear nonproliferation treaty.

The French president’s office said Macron, who sees the Iranian nuclear threat as sufficiently serious to justify the involvement of all five permanent members of the United Nations Security Council, had also stressed the need for Iran to cooperate fully with the International Atomic Energy Agency.

Iran’s parliament approved a bill last month to suspend cooperation with the IAEA, the UN’s nuclear watchdog, after Israel and the United States bombed Iran’s nuclear sites, aiming to prevent Tehran from acquiring a nuclear weapon. Iran has denied seeking one.

Macron “expressed his determination to seek a diplomatic solution that would lead to a lasting and rigorous resolution of the nuclear issue, the question of Iran’s missiles, and its role in the region,” his office said, adding that the two leaders had decided to “coordinate” their efforts.

France and Russia are both permanent members of the UN Security Council.
