Disagreements among European Union leaders over capping gas prices and national aid packages resurfaced on Friday as they met in Prague Castle to discuss how best to deal with the winter energy crisis, Reuters reported.

Fifteen EU member states want to set a maximum price for gas, but have not agreed on exactly how this should be done.

Germany, Denmark and the Netherlands oppose any cap, worried that it would make it harder to buy the gas they need to keep their economies afloat and reduce any incentive to cut consumption.

Austrian Chancellor Karl Nehhammer said any price cap must be designed and implemented in a way that supports energy suppliers.

“Negotiations are ongoing. And they will be intensive, because… our goal is to support… energy suppliers so that gas supplies do not decrease,” he said.

Czech Prime Minister Petr Fiala singled out a price cap for gas used to generate electricity, while Latvia’s Kristianis Karins said a cap would be “great” if the EU could still secure supplies from producers.

European Council President Charles Michel said no decision was expected on Friday, but hoped talks between the leaders would lead to an agreement at their next meeting on October 20-21.

“The energy crisis is a very important challenge that we have to solve,” Michel said, adding that he hoped the talks would make progress on reducing demand, securing supply and lowering prices. “I hope that we are taking steps in the right direction,” he added.

Poland fiercely criticizes Germany

Polish Prime Minister Mateusz Morawiecki is criticizing Germany for what he believes is overspending 200 billion euros in subsidies to protect consumers and businesses from rising energy prices.

“There will be very intensive discussions on this topic at the European Council. So the Italians couldn’t do it, the French couldn’t do it, the Poles couldn’t do it, but they can do it,” Morawiecki said Thursday night.

“If this is an equal, fair and just treatment of the principle of the common market of the European Union, then I am very sorry, but I do not understand it,” he added.

However, Alexandre De Croo of Belgium disagreed, saying that large national support packages were needed in the absence of European action.

“We can’t let people deal with cold weather. But the real solution is to act together in the market, and then these big (national) support packages will no longer be needed,” he told the press.

EU leaders will also discuss providing greater financial and military support to Ukraine in Prague. EU chief diplomat Josep Borrell said that it is important for all European countries, including those outside the EU, to stand in solidarity with Ukraine against Russian hostility.
