The United States may impose the toughest sanctions in history against Russia if no progress is made in resolving the conflict in Ukraine, US Special Presidential Envoy for Ukraine Keith Kellogg said in an interview with Fox News on May 13, 2025. According to him, the new restrictions could affect key sectors of the Russian economy, including the oil market and frozen assets, in order to force Moscow to the negotiating table. The statement reflects the Donald Trump administration's determination to increase pressure on Russia, but raises questions about the consequences for the global economy and the prospects for a diplomatic solution.

Kellogg stressed that the new sanctions would be “significant” and would surpass all previous measures imposed on Russia in severity. He noted that Washington is considering the possibility of influencing Russia’s “shadow fleet” – a network of tankers that transport about 70% of the oil through the Baltic Sea, as well as the frozen assets of the Russian Central Bank, estimated at $300 billion.

No details on this matter are given, however, it is obvious that they will appear against the backdrop of the expected meeting of the Russian and Ukrainian sides in Turkey.
