Morawiecki and Macron discussed Ukraine, energy and security in Paris

Speaking alongside Morawiecki at the Elysee presidential palace, Macron said there will be a first meeting in Prague in coming weeks to discuss creating a new European political community to address political and security-related challenges facing the continent, as well as Ukraine's and Moldova's candidate status in the bloc.

The main worry for now, Macron said, lies on ensuring the security of Ukraine's Zaporizhzhia nuclear plant.

"In the short term, the situation around the Zaporizhzhia plant is of course what worries us the most. We have done everything these past few days to help organise the IAEA mission. I spoke on the phone yesterday with (IAEA Director General Rafael) Grossi before he left early this morning to Ukraine. We have a common worry: first of all, nuclear safety and security should not be made fragile by this war. And so this mission is important, it should preserve this plant and the safety and security of the entire region," French president said.

Captured by Russian troops in March but run by Ukrainian staff, Zaporizhzhia has been a hotspot in a conflict that has settled into a war of attrition fought mainly in Ukraine's east and south six months after Russia launched its invasion.

A team from the U.N. nuclear watchdog headed on Monday to the Zaporizhzhia plant, the agency's chief said, as Russia and Ukraine traded accusations of shelling in its vicinity, fuelling fears of a radiation disaster.

Macron also said that Poland and France had been fighting "for several months to reinforce this energy sovereignty and to deeply reform the electricity market".

"I wish for us to fulfil this dynamic and to have a really have an electricity protected from elements of speculation and renovated in terms of identifying prices, since our countries today are victims of price formulas and basic market hypotheses that do no longer correspond to the reality. I wish for us to move forward very quickly, we have already called for this several months ago, and the coming weeks will be critical on this," he added.

Poland's Prime Minister Mateusz Morawiecki called for European solidarity in the face of the Ukraine situation.

"What we are dealing with today is not even the end of the war in Ukraine. Unfortunately, it is not even the beginning of an end. Maybe we just deal with the end of the beginning of the crisis, which is still developing on many levels, and that’s why our response needs to be patient, balanced, but also of course, firm," he said.

"We better not find out that the Ukrainians have more strength under Russian bombs that are falling on them, more strength, patience and resistance than us, Europeans who are sometimes hesitant to lower down our thermostat by two degrees," Polish PM added.

"Europe is now in a sort of geopolitical nap, and in the meantime, someone else is furnishing the world not necessarily the way we want it. That is why we either quickly wake up or the time will slip through our fingers and Europe will lose its significance in the geopolitical arrangement. Here in France, you don’t need to explain to anyone what it means to be one for all, all for one - the old Musketeers’ motto. This is the motto we should stick to, even if we differ in some matters," Morawiecki stressed.

"Joint Polish-French voice will serve to make us safer & to develop appropriate economic solutions that will stabilise the energy markets of the entire EU," Morawiecki's office quoted him as saying in a tweet later on Monday.

After meeting with Macron, Morawiecki also chaired a meeting with French businessmen in Paris.
