Vladimir Putin states Russia continues to be open to peace talks with Ukraine but demands discussions must align with the 2022 Istanbul agreements.
This fresh appeal for negotiations follows new strikes on Ukrainian refineries.
Reports indicate Putin's stance clashes with former president Donald Trump's latest changes on Ukraine policy.
Delegation meetings took place between Ukraine and the US in Florida to tackle major points during the present discussion.
The Russian leader emphasised that any future agreement cannot deviate from the terms established in Istanbul two years prior.
These conditions were set while military actions against energy infrastructure continued in the region.
