Greece blocked the package during a meeting of EU ambassadors, preventing the unanimous vote required for adoption. The core dispute was a proposed ban on the transit of Russian liquefied natural gas (LNG) through EU waters to third countries, scheduled to take full effect in 2027. Athens demanded an open-ended exemption for its shipping industry — specifically for one company, Dynagas — arguing the ban would "ruin" the firm.
The company is Dynagas, owned by Greek billionaire George Prokopiou. Dynagas specializes in transporting Russian LNG, particularly from Novatek's Yamal LNG project in the Arctic.
What made Greece's argument so specific — and so difficult for other EU members to counter — was the nature of Dynagas's fleet. The company operates 27 gas carriers, including specialized Arc7-class icebreaking LNG tankers designed to navigate Arctic ice. These vessels are among the world's most advanced icebreaking LNG carriers and were built specifically to serve the Yamal LNG project year-round. Greece argued that a ban on transiting Russian LNG would turn these specialized ships — which have no realistic alternative employment — into stranded assets worth hundreds of millions of euros, destroying Dynagas's core business.
Greece's EU ambassador told fellow envoys the proposed sanctions would cause "economic destruction" to Dynagas and, by extension, to a major sector of the Greek economy. The scale of Dynagas's role in the trade is stark: in February 2026, 17 of 21 Yamal LNG cargoes were transported by vessels linked to Dynagas and the UK-based Seapeak.
The package was proposed by the European Commission on 9 June 2026 and included far more than just the LNG transit ban:
The 21st package had a hard deadline of 15 July 2026 because the existing Russian oil price cap was due for its mandatory bi-annual review. Without an agreement, the cap would have automatically increased. Because Greece's veto blocked the entire package, the EU was forced to temporarily extend the existing price cap at $44.10 per barrel for one week to buy time for further negotiations.
EU diplomats were blistering in their comments. One called Greece's move "shameless." Another told Euractiv that the deadlock came down to "one single shipping company and one billionaire oligarch."
EU foreign policy chief Kaja Kallas, speaking at a press conference on 13 July 2026, stated: "Yes, I also regret that we do not have an agreement on the 21st package." She had previously expressed frustration with repeated sanctions deadlocks, saying the 20th package was "long overdue" and that delays send "a message we did not want to send."
This veto is part of a broader pattern of Greece resisting EU sanctions that threaten its dominant shipping industry, which controls the world's largest merchant fleet. Greece has repeatedly pushed back against oil price cap enforcement and shadow fleet measures that could affect Greek-owned tankers.
George Prokopiou has been publicly skeptical of sanctions. In June 2025, he told a maritime event: "Sanctions have never worked."
Greece, like Hungary, has become a recurring bottleneck for EU sanctions packages, often requiring last-minute carve-outs or delays to protect its maritime sector — a crucial part of its economy that generates massive tax revenue and employment.
As of July 17, 2026, the standoff remained unresolved, with the oil price cap extended week-by-week while EU ambassadors continued negotiations.
