In a telephone conversation with Chancellor Olaf Scholz (SPD) and French President Emmanuel Macron, Russian President Vladimir Putin warned against the delivery of heavy weapons to Ukraine.

This carries the risk of further destabilizing the situation and worsening the humanitarian crisis, Putin said, according to a statement published by the Kremlin in Moscow on Saturday.

In the 80-minute conversation, Scholz and Macron again called for an end to the war, as the spokesman for the federal government, Steffen Hebestreit, announced.

"The Chancellor and the French President pushed for an immediate ceasefire and a withdrawal of the Russian troops," Hebestreit said.

"They called on the Russian president to engage in serious direct negotiations with the Ukrainian president and to find a diplomatic solution to the conflict." According to the Kremlin, Putin emphasized Moscow's willingness to resume negotiations on a solution to the conflict, which were frozen "due to Kiev's fault".

The Kremlin said that the phone call also dealt in detail with food safety in the world.

The West, including Germany and France, is calling on Russia to end the blockade of Ukraine's Black Sea ports so the country can start exporting wheat again.

Putin once again blamed the "flawed economic and financial policies of Western countries" and the "anti-Russian sanctions" for the problems.

The federal government always points out that there are no sanctions against food.

Ukraine has accused Russia of blackmail in linking the fight against world hunger to the issue of sanctions.
