With ten rounds of sanctions, since Russia invaded Ukraine in February last year, the European Union has rolled out its toughest punishment ever against a foreign country.

The EU says its sanctions are meant to cut Moscow's revenues and access to technology used in war. But the impact "will not be severe enough to limit Russia's ability to wage war against Ukraine in 2023," a European Parliament research note said.

Much trade still flows between the bloc's 27 countries and Russia – a result of successful lobbying, the EU's unwillingness to take a harder economic hit, and concerns about ripple effects on global supply chains.

Rather than seek new sanctions, the EU now wants to crack down on bypassing those already imposed and officials identified the UAE, Türkiye, Armenia, Georgia, Kazakhstan and Kyrgyzstan as potential circumvention routes.

Here is a list of areas where the EU keeps on doing business with Russia.

Trade flows

In 2021, Russia was the EU's fifth-largest trading partner with goods exchange worth 258 billion euros, according to the EU executive European Commission. The main EU imports were fuel, wood, iron and steel and fertilizers.

Since the invasion in 2022, the value of EU imports from Russia fell by half to around 10 billion euros last December.

In total, the EU imported 171 billion euros worth of goods from Russia starting from March 2022 until the end of January 2023, according to the latest data available from Eurostat, the EU statistics office.

That figure thwarts the 60 billion the EU last month said it had assigned to Ukraine over the year since the invasion, though that total does not include the value of modern tanks Kyiv got since or the latest deal on ammunition supplies.

LNG

The EU sanctioned imports of Russian coal and seaborne oil last year. EU sanctions do not cover gas, but Moscow slashed pipeline deliveries to Europe since the invasion. In 2022, the EU received about 40% less Russian gas than in recent years.

Liquefied natural gas is another story. Russian LNG deliveries to Europe increased since the war – to 22 billion cubic meters (bcm) in 2022, up from around 16 bcm in 2021, according to EU analysis.

The LNG volumes are smaller than Russia's pipeline gas deliveries, which were about 155 bcm per year before the war. But the uptick has led some countries to ask for a legal option under EU law to block LNG imports.

Nuclear

Similarly, there have been no sanctions against Russia's nuclear industry, something Hungary – where Russian state nuclear energy company Rosatom is due to expand the Paks power plant – and Bulgaria openly oppose.

EU imports of Russian nuclear industry products totaled nearly 750 million euros in 2022, according to Eurostat. EU nuclear agency Euratom said Russia provided a fifth of uranium used by EU utilities in 2021, the latest data available, as well as a fourth of conversion and a third of enrichment services.

The French energy ministry disputed parts of a report by Greenpeace, which last month said Paris had sharply increased imports of enriched uranium from Russia since the invasion. Paris said its contracts with Russia would be more expensive to halt than continue.

Diamonds

The EU bought 1.4 billion euros worth of Russian diamonds last year, according to Eurostat, as it banned neither the gem imports nor blacklisted Russian state-controlled miner Alrosa.

Belgium, home to the world's biggest diamond trading hub Antwerp, has upset the bloc's hawks by lobbying against the EU going solo on Russian diamonds.

The EU, the United States and other G-7 economies are now working on a traceability system to squeeze out Russian diamonds together. The Antwerp World Diamond Centre said that needed to include India – not a G-7 member – to be effective.

Chemical and raw materials

EU imports of Russian fertilizers were worth 2.6 billion euros last year, over 40% up from 2021 as price rise beat reduced volumes, according to Eurostat.

Potash from Russia and its ally Belarus is heavily restricted or banned in the EU. But other fertilizers including urea flow freely, said Sean Mackle of industry lobby Fertilizers Europe, adding that the patchy approach weighed on implementation.

Disagreement among the 27 EU countries over proposed exemptions to keep fertilizers going to Africa is blocking more sanctions against Belarus for aiding Russia's war.

Among raw materials unaffected by sanctions is nickel, mostly used for stainless steel production. The EU imported 2.1 billion euros worth of nickel in 2021, up to 3.2 billion euros last year, according to Eurostat.

Big names and secondary sanctions

Alrosa and Rosatom are missing from the EU's blacklist which currently covers nearly 1,700 individuals and entities banned from the bloc. Gazprombank – the financial arm of Russia's gas monopoly Gazprom – and Russia's privately owned, second-largest oil producer Lukoil are also missing.

Transparency International has long called for a cut in Russia's access to EU lobbying and for secondary sanctions to punish those helping others already under sanctions, as is standard practice in the United States.
