Vice President JD Vance requested that Ukraine cease its attacks on oil tankers transporting crude oil through Russian ports in the Black Sea, citing potential disruptions to global energy markets. This communication occurred during a call between Vance and Ukrainian President Volodymyr Zelensky on July 31, where they discussed the impact of Russia's war on global markets. A report from the Financial Times, citing Ukrainian officials, indicated that Ukraine was pressured to halt attacks on non-Russian tankers carrying Kazakhstani oil to a terminal at Novorossiysk port.
A senior Ukrainian official stated, 'We very carefully listen to our American partners.' Previously, the U.S. Department of State expressed concerns regarding Ukrainian naval operations in the Black Sea, emphasizing that discussions were focused on protecting American economic interests rather than limiting Ukraine's military actions against Russian infrastructure.
Despite the request to pause attacks on oil tankers, Zelensky announced that Ukraine successfully conducted drone and missile strikes against Russian military targets at the Novorossiysk naval base, which is over 300 kilometers from the front line. Zelensky confirmed that the operation targeted air defense positions and seaport infrastructure.
The European Union's recent policy allows for the seizure and sale of Russian oil being transported illegally, which could enhance Ukraine's military efforts. So far in 2026, the EU and UK have seized five Russian oil tankers, although three were released by France.
In response, Russian President Vladimir Putin condemned these actions as 'piracy' and threatened retaliation against Western nations if such policies are enforced. He stated that Russia would respond wherever deemed necessary, including in the Pacific Fleet’s area of responsibility, and noted that his military is monitoring maritime traffic closely.
