The United States hit Russia with tougher sanctions in late 2025. The aim was to cut war income and push Moscow toward peace talks.
That pressure did not end the war. By September 2026, the fighting was still active. New U.S. peace talks had begun, but no deal had been reached. Europe had also added new sanctions of its own.
What Changed in Late 2025
On October 22, 2025, the U.S. Treasury sanctioned Rosneft and Lukoil. They are two of Russia’s largest oil firms. Treasury said the move would raise pressure on Moscow and cut funds for the war.
The European Union acted one day later. Its 19th sanctions package hit Russian energy, banks, crypto firms, and the shadow fleet used to move oil.
This changed the picture. The United States did not just wait for Europe. Washington acted first, and Europe also moved.
Why Europe Still Matters
Sanctions work best when big markets act together. If one nation acts alone, Russia can seek new buyers, banks, ships, and trade routes.
Europe is key because it is close to Russia. It also has deep trade and energy ties in the region.
Our guide to NATO in 2026 shows why defense, energy, and money now overlap in Europe.
The EU has cut its use of Russian gas since 2022. Still, the shift is hard. Some states worry about price, supply, and winter demand.
Why Oil Is a Main Target
Oil and gas sales bring cash to the Russian state. That is why the West keeps a close eye on energy trade.
The U.S. Treasury’s official Rosneft and Lukoil notice said the goal was to cut funds that help Russia’s war effort.
The rules also affect firms that deal with those companies. Banks, traders, shippers, and insurers must check who is on each deal.

Europe Kept Adding Pressure
The EU added more Russia sanctions in 2026. New steps hit parts of the arms industry, oil trade, and shadow fleet.
Sanctions are not one rule. Some block bank deals. Some freeze assets. Some limit oil, ships, parts, or tech.
The hard part is making the rules work. Russia can try to hide who owns a ship or firm. It can also route trade through other states.
That is why the shadow fleet matters. Old tankers and hard-to-trace owners can help move oil outside normal channels.
Frozen Russian Assets
Europe also holds a large pool of frozen Russian state assets. Ukraine wants more of that money used for its defense and repair work.
But frozen does not mean seized. Taking the money raises legal and financial risks. EU states still debate how far they can go.
Our look at the Zelensky peace plan explains why money is only one part of the talks. Land and long-term safety are still major issues.

What Changed by September 2026
Sanctions are now one part of a wider U.S. push.
U.S. envoys met Vladimir Putin in Moscow in early September 2026. They later met Ukrainian President Volodymyr Zelensky. The talks produced new ideas, but no clear break in the deadlock.
Russia and Ukraine still disagree on land and security. Ukraine rejects demands to give up large areas. Russia still seeks terms Kyiv says would reward the invasion.
Our article on how Putin could reach Hungary with an ICC warrant shows how law and diplomacy can add more pressure around the war.
Europe Is Being Asked to Pay More
The Trump team has also asked Europe to carry more of the cost.
In September 2026, Trump said Europe should repay the United States for some past aid to Ukraine. That fits his wider push for allies to spend more on their own defense.

What Sanctions Can Do
Sanctions can make trade harder. They can block cash, parts, tech, ships, and markets.
But they cannot force peace on their own. Russia has found new buyers and new trade paths outside the West.
So the key test is simple. Do the rules change Russia’s choices over time?
What to Watch Next
Watch the next round of U.S. peace talks. Russia said on September 9, 2026, that it hoped talks with Ukraine would restart soon.
Watch Europe too. The EU still plans more steps against Russia. It also faces hard choices over energy and frozen assets.
The old question was whether Washington would act only after Europe moved. We now know the answer is more complex. Both have acted. The next test is whether pressure, aid, and talks can help move the war toward a lasting peace.
