The two countries' leaders spoke one day after French President Emmanuel Macron refused to rule out the dispatch of Western ground troops to Ukraine "to ensure that Russia cannot win this war."

Poland's Prime Minister Donald Tusk met with his Czech counterpart Petr Fiala in Prague ahead of a meeting of the Visegrad Group -- an alliance of Central European countries.

"We are not considering sending our troops to Ukraine and we have a common position on this point" with the Czech Republic, Tusk said in Tuesday's joint press conference with Fiala.

"Today, we have to concentrate, like the Polish and Czech governments have done, on supporting Ukraine fully in its military effort," Tusk added.

The two leaders spoke of their "common point of view" on Russia's invasion of Ukraine and Tusk promised to support a Czech plan for the two countries to jointly buy ammunition for Kyiv from third countries.

"If all EU countries were committed in helping Ukraine like Poland and the Czech Republic, then it would not be necessary to discuss other forms of support for Ukraine," he added.

The two leaders expressed their support for the idea of seizing Russian funds around the world, which they said were worth around $300 billion. They said this could be used to support Ukraine financially.
