The European Union merits recognition for implementing its 21st sanctions package targeting Russia. Each additional step that curtails the Kremlin's capacity to fund its conflict with Ukraine is significant.

Yet this newest package also sets a troubling precedent.

To achieve full consensus, the EU apparently provided Greece with a renewable waiver permitting European shipping firms to keep moving Russian liquefied natural gas to non-EU destinations under pre-invasion agreements.

The allowance is likely to aid Dynagas, the Greek shipping firm led by billionaire George Prokopiou, whose specialized ships are essential for supporting Russia's Yamal LNG initiative.

Dynagas possesses or operates five specialized Arc7 LNG carriers dedicated to Yamal LNG, Russia's primary LNG export site.

These represent no ordinary ships that can be swapped out readily. Built for continuous Arctic operations, Arc7 carriers are advanced specialized tools that allow Russia to ship LNG from one of its key energy sites to worldwide markets.

Put differently, these vessels do more than carry Russian gas. They form part of the system enabling Russia's Arctic LNG shipments.

This is why they count. LNG now ranks among the Kremlin's top remaining export areas, with Yamal LNG at its core.

Europe had spotted a vulnerability Russia cannot readily substitute. Rather than fully using that advantage, it arranged a workaround.

Athens' stance

Backers of the Greek view claim that limiting European operators would merely shift the activity to rivals from China or other places without much impact on Russian income.

At first view, this seems practical. In truth, it opposes nearly all effective sanctions.

Excluding European maritime skills and specialist Arc7 vessels from Russia's LNG chain would not halt Russian shipments immediately.

It would, though, heighten the operational difficulties for one of Russia's key energy sectors.

This matches what sanctions aim to achieve. Instead, the reported deal permits ongoing operations.

This waiver proves hard to defend since it involves LNG shipments to nations outside the European Union. The matter is not about Europe requiring Russian gas for heating or industry. The concession safeguards commercial shipping services aiding Russia's worldwide LNG trade beyond EU borders.

This difference is key.

Europe faces no choice between energy needs and support for Ukraine. It decides if European firms should keep profiting from vital services to Russia's LNG sector. The response ought to be direct.

The Dynagas issue also fits a wider trend. Data from the Centre for Research on Energy and Clean Air shows Greek-controlled ships have moved about 248 billion euros in Russian fossil fuels since the full invasion began, exceeding any other nation's vessels.

Greek-controlled tankers have handled roughly 135 billion euros in Russian oil products, while Greek-linked vessels have carried about 23 billion euros in Russian LNG.

These numbers highlight the extent of Greece's business links to Russia's fossil fuel exports.

Retaining this waiver sends the incorrect message. It indicates to businesses that substantial commercial stakes might gain exemptions over time. It shows member states that holding back agreement can lead to better results. And it signals to Moscow that Europe's political cohesion stays open to negotiation when powerful sectors are involved.

Another concern needs more focus. If European operators eventually exit this field, Russia will seek ways to keep using these specialized assets.

This poses a clear risk that Arc7 vessels could be sold, moved or restructured via intermediaries before limits fully apply.

Europe must not let today's waiver turn into tomorrow's evasion route.

The EU should set immediate strict rules blocking the sale, transfer or reflagging of Arc7 LNG carriers to Russian firms or third-party entities acting for Russia. Any effort to maintain these services via ownership or corporate shifts should prompt further sanctions.

'Temporary' must stay temporary

Just as vital, the current waiver must remain exactly that: temporary. A short transition period can sometimes be warranted to end existing contracts. But renewable waivers that keep the core activity risk turning into lasting gaps. The duty falls on those wanting extensions to prove they serve a strong European goal, not just individual company profits.

Dynagas also holds options. The firm can keep depending on political deals to sustain business aiding Russia's LNG exports. Or it can see that its special skills now matter for Europe's shared security and set a clear schedule to end its role in the Yamal LNG trade.

Greece faces options too.

Athens has repeatedly voiced backing for Ukraine and European unity against Russian aggression. It should align those words by aiding Europe to seal sanctions gaps instead of seeking exceptions that maintain business ties to Russia's energy field.

This error must now be fixed. The waiver should end on schedule, receive no renewal, and Europe must ensure no specialized vessels, deals or ownership setups serve to bypass its sanctions.
