Kaczynski accused Moscow of using its energy policy to blackmail Europe, which depends heavily on imported Russian oil and gas.
It is in the European Union's interests to diversify sources of energy, but "the situation in Georgia is complicating this," he said.
"I think it was Russia's aim to make it more complicated," Kaczynski said after meeting the presidents of the Czech Republic, Hungary and Slovakia in the spa town of Piestany.
He said diversification did not mean that the EU should stop buying Russian energy, but he called on Moscow to change the way it deals with its partners.
"An element of blackmail cannot be included in the energy policy of our partner," Kaczynski said.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
