Greece blocks Russia shipping sanctions

For two weeks at the start of July, something changed on the waters around occupied Crimea. Between 30 June and 11 July, the number of vessels broadcasting their location in the Sea of Azov fell by 55% (NV.ua/ISW, Adevărul). Russia temporarily shut the Kerch Strait and the Don-Azov Canal to shipping applications (Berlingske). Its agriculture ministry began preparing overland alternatives (Al Jazeera).

That is the useful evidence. Claims about wartime damage are always contested, but behaviour is harder to disguise. When ships go dark, waterways close and ministries start planning detours, the pressure is being felt.

Ukraine's maritime strike campaign is now creating real friction in the supply chain that moves fuel, cargo and military supplies to occupied Crimea and the southern front. Kyiv is hitting the same fuel-and-shipping network the EU says it wants to squeeze through sanctions. The difficulty is that the EU's sanctions machinery has stalled.

What Ukraine Is Targeting

Ukraine is not chasing individual ships for the look of it. It is going after the system that makes those ships useful: fuel depots, refineries, tankers, ferries, tugboats and coastal freighters that turn crude into diesel and move it to where Russian forces need it. German reporting has described the campaign as simultaneous pressure on fuel processing, storage and maritime transport towards Crimea (tagesschau, Deutschlandfunk).

Kyiv does not need to sink every vessel. If Russia has to reroute cargo, spread fuel stocks more thinly, close waterways and push supplies onto longer overland routes, the cost of holding the southern front rises day by day (t-online).

Ukraine says more than 100 vessels were hit in roughly nine days. Danish and Cypriot outlets carried those figures, while making clear they came from the Ukrainian side and had not been independently verified (Politiken, Euronews Greek). The firmer evidence is still the pattern of response: ships disappearing from tracking systems, canals closing, and contingency plans being announced in public.

Greece Blocks What Ukraine Bombs

Ukraine is striking ships and fuel sites. The EU is trying to make the same network harder to insure, service and finance. On 15 July, EU ambassadors in Coreper, the committee that prepares decisions for ministers, failed to agree the 21st sanctions package. The package was meant to tighten rules on shadow-fleet vessels and LNG transport (Handelsblatt, Baird Maritime).

Foreign-policy sanctions in the EU require unanimity under Article 29 of the Treaty on European Union, the clause governing the bloc's common foreign and security policy. In practice, that gives every member state a veto, or at least the power to force dilution (Article 29 TEU). Greece used that leverage.

Athens argued that the package would damage European competitiveness. Greek-owned ships reportedly carried about 15% of Russian crude exports in May 2026, earning at least $4 billion over three years within the legal framework of the price cap (Newsit/Reuters, FinanceNews). It also resisted restrictions on transporting Russian LNG to third countries. This is not a vague argument about competitiveness. It touches specific commercial exposure, including Dynagas, whose specialised Arctic tanker fleet is built for the Yamal LNG route (Euronews Greece).

The Commercial-Political Contradiction

Romania shows where the two tracks collide. Ukrainian strikes against Russian supply lines are useful for NATO's eastern flank. But proximity brings its own danger. On 5 June, a Ukrainian maritime drone exploded in Romania's port of Constanta after Kyiv said it had lost control of four drones, probably because of Russian electronic warfare (Adevărul).

That is the awkward edge of the policy. The war creates immediate physical risks for neighbouring states, while the regulatory response still turns on the slower question of whether a vessel is on a sanctions list.

The record supports a plain conclusion: EU unanimity is, for now, protecting commercial exposure inside the same maritime system Ukraine is trying to disrupt, at least where the reported Greek objections concern shipping and LNG transport. Drones are moving faster than diplomacy. Until the 21st package passes, Europe's legal tools for raising Russia's logistics costs remain stuck, while Ukraine's physical tools continue to work.
