Analysis of the EU's 21st Sanctions Package Against Russia: The Dual Structure of Energy Sector Pressure and Exemptions

Executive Summary

The EU's 21st sanctions package against Russia strengthened pressure on the energy sector by recalibrating the oil price cap and cracking down on the “shadow fleet.” However, it also revealed a dual structure, with coexisting exemptions for Greek vessels transporting Arctic LNG and for South Korea and Japan regarding the Sakhalin-2 project. The fact that EU member states purchased 92% of Russia's LNG exports in the first seven months of the year highlights the gap between the tough rhetoric of High Representative Kallas and the actual behavior of member states. Given the unanimity requirement among the 27 member states, the upcoming 22nd package in the fall will likely see a repeat of pressure for new exemptions, similar to the opposition from Hungary and Slovakia regarding Rosatom. South Korea must manage the persistent risk of renegotiating its Sakhalin-2 exemption and the potential for maritime physical conflict over the shadow fleet crackdown as separate tracks. It also needs to proactively incorporate clauses into its energy procurement contracts and compliance systems to address potential changes in the sanctions regime.

I. Situational Analysis

The EU's 21st Sanctions Package Against Russia: A Situational Analysis

1. Background and Developments

The EU's sanctions against Russia have accumulated through 21 packages since Russia's full-scale invasion of Ukraine in 2022. According to the Brookings Institution, the core of the 21st package, announced on July 23, is the energy sector [3]. The oil price cap was fixed at $44 per barrel until July 2027 [3]. Transactions with certain Russian oil refineries were also restricted [3]. The package also included a monitoring system for LNG carriers and a ban on the transport of Russian LNG [3].

This ban on LNG transport came with an exemption. Greek vessels transporting Russian LNG from the Arctic were excluded from the sanctions [3]. This exemption is an example that clearly shows the fissures within the EU sanctions regime. According to The Kyiv Independent, the Greek shipping company Dynagas delivered Russian LNG worth €2.35 billion to EU customers between January and July 2026 [4]. This amount corresponds to more than one-fifth of Russia's LNG exports during the same period [4]. This is because EU leaders granted Dynagas an exemption allowing it to continue transporting to third countries even after the ban on LNG imports takes effect in January 2027 [4].

The 21st package added 40 vessels from the so-called “shadow fleet” to the sanctions list [3]. This is the fleet Russia has built to export its crude oil independently, circumventing the G7 price cap [3]. A provision directly affecting Asian countries was also included. According to The Kyiv Independent, the EU extended the exemption for South Korea and Japan to import crude oil from the Sakhalin-2 project in this package [8]. At the same time, it created a new exemption excluding LNG supplies from the same terminal from the sanctions [8]. This can be interpreted as a result of the EU explicitly considering the energy security of South Korea and Japan.

2. Current Situation

Since the announcement of the 21st package, a debate over the effectiveness of the sanctions has continued within the EU. The German daily Die Presse, citing a new data analysis by the environmental group Urgewald, pointed to the EU's dual standards [9]. In the first seven months of this year, EU member states purchased 92% of Russia's total LNG exports [9]. This amounted to over €6 billion flowing into Russia's war chest [9]. The fact that a few member states are absorbing virtually all of Russia's LNG production highlights the discrepancy between High Representative Kallas's tough rhetoric and the actual import behavior of member states [9].

In a mid-August written interview with the German daily Die Welt, EU High Representative for Foreign Affairs and Security Policy Kaja Kallas announced a 22nd package for the fall. She stated, “In the fall, we will present the most extensive list of sanctions since the beginning of the war” [1][6]. She mentioned that if this list is adopted, the number of sanctioned Russian individuals, companies, and institutions will immediately increase by one-third [6]. The South China Morning Post reported Kallas's statement that EU sanctions have already deprived Russia of over €1 trillion in its ability to wage war [1].

Russia is also taking countermeasures. According to TASS, the Russian government, led by Deputy Prime Minister Alexander Novak, announced a plan to minimize the risk of fuel market shortages by optimizing the maintenance schedules of its oil refineries [11][15]. This suggests that Russian authorities are proactively responding to the pressure on their refining sector from the sanctions. The U.S. Department of the Treasury extended a general license exempting from sanctions the negotiations for the sale of Lukoil's foreign assets until September 19 [12]. This shows that the enforcement of sanctions against Russia is not being carried out in perfect lockstep, even within the Western bloc.

3. Key Actors and Positions

The European Commission and the High Representative (Kallas)maintain a stance of continuously increasing the intensity of sanctions. Kallas reaffirmed this hardline approach by announcing the fall's 22nd package as the “most extensive” measure “since the beginning of the war” [1][6]. However, in the actual implementation process, the constraint on negotiating power due to the member state unanimity requirement remains a constant factor.

Greeceis the actor that secured the LNG transport exemption, reflecting the interests of its shipping industry. The Dynagas case shows that Greece has protected the revenue base of its shipping companies even within the sanctions framework [4].

Energy-Dependent Countries, including Hungaryhave used the unanimity requirement to dilute the intensity of sanctions. The South China Morning Post points out that this requirement has caused previous packages to be plagued by prolonged disputes among member states [1].

The Russian Governmentis focused on managing the impact of sanctions through practical measures such as adjusting refinery maintenance schedules [11][15]. At the same time, it is pursuing a strategy of maintaining exports to Asia through existing supply chains like Sakhalin-2.

South Korea and Japanare the parties that have received exemptions for Sakhalin-2 crude oil and LNG within the EU sanctions regime [8]. This is a result of the EU explicitly considering their energy supply and demand structures, and the continuation of this exemption could become a key issue in the upcoming 22nd package negotiations.

Ukraineis an actor that consistently pressures for sanctions against Rosatom. On August 17, Foreign Minister Andrii Sybiha cited a Politico report about safety culture violations found at Rosatom's nuclear power plant project in Egypt, urging the EU once again to include it in the sanctions [14].

4. Key Issues

The first issue is the extent to which exemptions undermine the effectiveness of the sanctions. The LNG transport exemption for Greek vessels and the Sakhalin-2 exemption for South Korea and Japan both leave structural loopholes in the sanctions regime [3][4][8]. The fact that EU member states purchased 92% of Russia's LNG exports this year starkly illustrates this structural problem [9].

The second issue is the negotiation delays caused by the unanimity requirement. The possibility of a veto by some member states, such as Hungary, remains a constant factor in the discussions for the 22nd package, and this constraint is expected to be particularly prominent for highly symbolic measures like sanctions on Rosatom [1][14].

The third issue is that the crackdown on the shadow fleet is translating into maritime logistics risks. The sanctioning of an additional 40 vessels is a measure targeting Russia's circumvention export network [3], but this has subsequently led to Russian warnings of retaliatory seizures, acting as a factor heightening maritime tensions.

II. In-Depth Analysis

The EU's 21st Sanctions Package Against Russia: An In-Depth Analysis

1. Analysis of Root Causes

The reason the 21st package focuses on the energy sector is simple: after three and a half years of sanctions, the energy-dependent structure of Russia's finances has not been shaken. The Brookings Institution identified the measure to refreeze the oil price cap at $44 per barrel as a key element of the 21st package [3]. This downward adjustment is based on the assessment that the previous $60 cap had already been rendered ineffective compared to the actual discounted prices of Russian crude. This means the structural flaws inherent in the price cap scheme from its inception have been recurring for three years.

A more fundamental cause lies in the conflicting interests of EU member states. Die Presse, citing data from Urgewald, reported that EU member states purchased 92% of Russia's total LNG exports in the first seven months of this year [9]. This amounted to over €6 billion flowing into Russia [9]. As long as the structure where a few member states absorb most of Russia's LNG production is maintained, the real deterrent effect of the sanctions is bound to be limited, no matter how tough High Representative Kallas's statements are. The headline of this report, “EU gas imports fill Putin's war chest with over 6 billion euros,” itself encapsulates the EU's internal contradictions [9].

The exemption for Greek vessels transporting Arctic LNG is also a product of the same context. The Kyiv Independent reported that the Greek shipping company Dynagas delivered Russian LNG worth €2.35 billion to EU customers between January and July 2026 [4]. This corresponds to more than one-fifth of Russia's LNG exports [4]. This can be interpreted as the result of Greece's shipping industry interests being prioritized over the EU's common sanctions principles.

2. Structural Context

Political Structure: The Unanimity Requirement and Veto Politics

The fundamental constraint of the EU sanctions regime is the unanimity requirement among its 27 member states. The South China Morning Post noted that this requirement has caused previous packages to be plagued by prolonged disputes among member states [1]. The possibility of a veto by some member states, including Hungary, acts as a constant factor. This structure institutionally allows individual member states to use their national energy and industrial interests as leverage to dilute the content of the packages. The Greek LNG transport exemption and the potential for Hungary and Slovakia to block sanctions on the nuclear sector are all consequences derived from this unanimity structure.

Economic Structure: The Asymmetry of Energy Dependence

Within the EU, dependence on Russian energy varies greatly among member states. This asymmetry is the fundamental factor that delays sanctions discussions each time. While some member states have already secured alternative LNG suppliers, others remain substantially dependent on Russian energy. TASS reported on a story from the German newspaper Handelsblatt suggesting that European gas storage facilities could be completely depleted by April 2027 as injection rates slow due to the fallout from U.S.-Iran tensions [10]. As long as such supply instability exists, a complete cutoff of Russian energy is politically difficult to achieve within the EU.

Security Structure: The Potential for Physical Conflict over Maritime Logistics

The crackdown on the shadow fleet is already escalating into physical tension at sea. This differs in nature from previous sanctions packages because it means sanctions could move beyond financial and trade restrictions on paper to the use of physical force, such as seizures and inspections. Russia's warning of retaliatory seizures shows that the enforcement phase of the sanctions is shifting from diplomatic friction to a maritime security risk [12][13].

3. Historical Precedents and Comparison of Similar Cases

The repeated downward adjustments of the price cap are an extension of a pattern seen since the initial $60 cap was introduced in December 2022. Whenever the gap between the market price and the cap has widened, the EU has readjusted the cap, and Russia has responded by expanding its shadow fleet and finding new workarounds. The latest freeze at $44 and the sanctioning of 40 additional vessels are merely the newest phase of this cat-and-mouse game; the underlying structure has not changed [3].

The dilution of sanctions' effectiveness through exemptions is also a recurring pattern from previous packages. The extension of the exemption for South Korea and Japan regarding the Sakhalin-2 project is a prime example [8]. According to The Kyiv Independent, in the 21st package, the EU not only maintained the exemption for importing crude oil from Sakhalin-2 but also created a new exemption for LNG supplies from the same terminal [8]. This represents a repeat of the EU's practice of finding a compromise between the energy security of its members and allies and its pressure campaign against Russia.

The deferral of sanctions on Rosatom is following a similar trajectory. On August 17, Ukrainian Foreign Minister Sybiha urged the EU to reconsider sanctions on Rosatom, citing a Politico report that found safety culture violations and numerous safety, security, and engineering flaws in Rosatom's project in Egypt [14]. This reaffirms that sanctions on the nuclear sector have been continuously postponed, both in the 21st package and in previous ones. As long as Hungary and Slovakia's dependence on Rosatom remains unchanged, this pattern is highly likely to repeat itself in the 22nd package.

4. Key Variables Shaping Future Developments

The first variable is the level of U.S. cooperation on sanctions against Russia. TASS reported that the U.S. Treasury extended a general license exempting negotiations for the sale of Lukoil's foreign assets from sanctions until September 19 [12]. This can be read as a signal that the United States does not intend to completely block the market-driven disposal of assets belonging to major Russian oil companies. As long as this difference in temperature exists between the EU's hardline stance and the U.S.'s pragmatic approach, the coherence of the Western sanctions coalition will continue to be tested.

The second variable is Russia's capacity to maintain and repair its oil refineries. TASS reported that the Russian government, in a meeting chaired by Deputy Prime Minister Novak, set a goal to minimize the risk of fuel market shortages by optimizing refinery maintenance schedules [11][15]. This can be seen as a preemptive, government-level response by Russia to the EU's restrictions on transactions with refineries. If this response is successful, the effectiveness of the EU's sanctions on the refining sector may be limited.

The third variable is whether the crackdown on the shadow fleet and retaliatory seizures will actually lead to a conflict in the 22nd package. As the commander of Russia's Pacific Fleet has stated they are prepared to “inspect and detain” vessels from hostile nations, the possibility of an accidental clash in the Black Sea or Baltic Sea cannot be ruled out if European countries actually seize Russian tankers. In that case, sanctions could transform from a tool of economic pressure into a trigger for military tension.
