Russia's allies in Eastern Europe say Brussels plans to end all Russian gas and energy imports in the coming years, which is related to "economic suicide" and threats to the region's energy security and economy.

The European Commission announced on Tuesday that it plans to phase out Russian gas, nuclear and liquefied natural gas (LNG) imports by the end of 2027, saying the move “paves the way to ensure the EU is in full energy independence away from Russia.”

Russia's invasion of Ukraine in 2022 prompted the EU to ban most ocean imports of Russian oil, coal and refined petroleum products, but reducing airflow has proven to be more difficult. According to the European Commission, less than 19% of the EU’s natural gas and liquefied natural gas imports still come from Russia in 2024, although 45% of the region comes from major oil and gas exporters, although 45% of the region comes from 2021.

The latest EU proposal has already sparked an angry reaction from Eastern European countries, which have traditionally relied on Russia’s cheap energy supply and have repeatedly warned consumers of higher energy prices due to banning such supplies.

The Slovak and Hungarian governments maintained warm ties with Moscow despite the war in Ukraine, and they described the EU's latest plan as a "serious mistake" that harmed the region.

"We recognize the strategic goal of reducing energy dependence on third countries, Slovakia is ready to do this with the EU, but...it's just economic suicide just agrees that natural gas, nuclear, nuclear, nor oil (can be imported from Russia (can be imported from Russia), everything has to end, just because the comments between the Western world and other countries are established between Russia and other countries, the Slovak couple on Wednesday, Robert Robert (Slovak).

Hungarian Foreign Minister Péter Szijjártó said on Wednesday that the EU's proposal was "politically motivated" and "serious mistakes."

The minister told X: "It threatens energy security, raises prices and violates sovereignty. They want us to bear the cost of reckless support for Ukraine and its hastily EU joining. We firmly reject that."

Both Hungary and Slovakia have opposed previous EU initiatives to cut energy relations with Moscow, rather than choosing to maintain supply due to concerns about increasing energy costs at home.

Both have also been criticizing Ukraine for providing more military and financial aid and have previously threatened to refuse to support EU regular sanctions on Russia. Both hope to withdraw the offer from the group before approving its renewal in March.

The EU said in announcing its latest plan to get away from Russia that the “roadmap” of phasing out all energy imports of Russia will first introduce a ban on Russian natural gas (pipeline and liquefied natural gas) under new contracts and will take effect by the end of 2025, then by the end of 2025, and then by the end of 2022.

The committee's legislative proposal, to be proposed in June, will require approval from the European Parliament and qualified majority member states, meaning the plan cannot be rejected by only a few countries.

“We can adopt it without consistency,” European Energy Director Dan Jorgensen said in a press conference Tuesday.

He added that the group is currently in an “unacceptable situation” where it depends on the Russian state and leader, President Vladimir Putin, who “choose to weaponize energy”. He added that imported Russian gas has indirectly helped fill the Kremlin's "war box" to continue the war with Ukraine.

In a statement Tuesday, the committee said it envisions a "step-by-step and coordinated" approach to the entire group and asked member states to prepare national plans by the end of the year to "explain how they will promote the phase-out of Russian gas, nuclear energy and oil imports". Not sure whether Slovakia and Hungary will join the requirement.

CNBC has asked the Kremlin to respond to the EU's proposal and is awaiting a reply.
