I'm sorry, I'd looked to see what Zelensky had said and missed that bit.Drivel as usual.
“We’ve seen how many ties your companies have with Russia,” he said in an address to the Bundestag, “with a country that just uses you and other countries to finance its war.”

Having said that, I'm not sure how fair it is. Ukraine traded with Russia, $6.62bn imports in 2019 (with $4.69bn exports) so you could argue Ukraine was financing Russia.
That's dwarfed of course by the $50bn paid by European countries for Russian gas, but Ukraine has bought Russian gas (or latterly bought it from EU countries who've bought gas from Russia).
