• Ukrainian President Zelensky states that Russia is losing the initiative on the battlefield in its war against Ukraine, potentially opening the door for a diplomatic resolution.
• Zelensky highlights that the Russian army has been suffering heavy losses since the end of December, with the Ukrainian military regaining more territory than the invading force is occupying.
• Zelensky calls for increased internal and sanctions pressure on Putin, as well as European involvement in negotiations, to capitalize on Russia's weakened position and seek a diplomatic solution before the next winter.

Russia is losing the initiative on the battlefield in its war against Ukraine, paving the way for a diplomatic solution to the conflict, Ukrainian President Volodymyr Zelensky said on Sunday.

In an interview with US broadcaster CBS, Zelensky said the Russian army has been increasingly on the back foot since the end of December, suffering heavy losses.

The Ukrainian military is recapturing more territory than the invading force is occupying, he said, adding that Russian President Vladimir Putin is responding to the losses by increasing the intensity of his bombing campaign against Ukraine.

Russia's weakness offers an opportunity for a diplomatic solution before the onset of next winter, Zelensky argued.

However, he added that this would require internal pressure on Putin as well as increased sanctions pressure from the US and Europe.

Europe, too, must be at the negotiating table, possibly in a trilateral format involving the UK, France and Germany, he suggested

Previous attempts at negotiation or mediation have failed due to Moscow's uncompromising positions. These include the demand that Kiev must withdraw its army from areas in the eastern Donbass region – comprising the Donetsk and Luhansk provinces – that have not yet been captured by Russia.

Zelensky criticized the easing of sanctions against Russia in the face of the oil crisis caused by the US war against Iran.

"Lifting sanctions is a help for the soldiers of Russia," he argued. The easing of sanctions against Moscow has not led to any surprises such as lower global prices for oil, petrol or diesel, according to the Ukrainian president.
