A Commission spokesperson confirmed the Fico meeting would be postponed, but did not say to when.
Fico was also scheduled to meet with Europe’s Energy Commissioner Dan Jørgensen.
“As usual, man makes up his mind and God changes his mind,” Fico told reporters on the plane back to Bratislava in a video posted on his Facebook page.
Fico said he planned to return to Brussels on Monday to attend an informal European Council summit, but in addition to meeting EU leaders, he would also try to talk one-on-one with von der Leyen and Jørgensen about a gas deal. “The issue is of enormous importance,” Fico said.
Earlier this week, Fico had called Zelenskyy an “enemy” of Slovakia due to the gas transit dispute.
