Ukraine has halted strikes on the Russian Black Sea port of Novorossiysk following a request from U.S. Vice President James David Vance, according to Ukrainian officials cited by the Financial Times. The agreement aims to prevent further instability in global oil markets and protect American corporate interests tied to Kazakh crude oil exports.
U.S. Intervention to Protect Caspian Pipeline Consortium
During a conversation on July 31, Vice President James David Vance asked President Volodymyr Zelenskyy to stop attacks on the port, according to Ukrainian officials and sources familiar with the matter. Washington expressed concern that Kyiv’s targeting of oil tankers was destabilizing petroleum markets and harming U.S. companies.
The primary point of contention is the Caspian Pipeline Consortium (CPC) terminal in Novorossiysk. This terminal serves as the main export route for oil from Kazakhstan. According to the Financial Times, Ukrainian authorities agreed to stop attacking CPC infrastructure and non-Russian vessels, provided those ships are not under Ukrainian sanctions and are not carrying Russian oil or cargo.
Did you know? The Caspian Pipeline Consortium is a critical energy artery for Central Asia, linking Kazakh oil fields to the global market via the Russian coast.
U.S. Energy Giants and the Stakes in Kazakhstan
The U.S. government’s interest in the port is tied to significant investments by American energy firms. Chevron and ExxonMobil both hold stakes in the CPC and the western Kazakh oil fields that feed the pipeline, according to the Financial Times.
Chevron owns 50% of Tengiz, the largest oil field in Kazakhstan, while ExxonMobil holds a 25% stake. These assets rely on the Novorossiysk terminal for export, making any disruption to the port a direct financial risk to these U.S. corporations.
Impact of Ukrainian Strikes on Oil Logistics
Ukrainian attacks on the CPC terminal last month, combined with a campaign against shipping in the Sea of Azov, created significant operational chaos. The Financial Times reports that these strikes forced Kazakhstan to repeatedly halt oil transport to Novorossiysk.

The instability led to a sharp increase in costs for the shipping industry. Insurance premiums and transport prices more than doubled following the attacks, according to the report.
A senior Ukrainian official stated that Kyiv “listens very carefully” to its American partners and has established specific “mechanisms” to ensure the agreement is upheld. Since the July 31 request, the Financial Times reports that Ukraine has not attacked tankers near the CPC terminal.
Comparative Reporting on the Request
While the Financial Times provided detailed context regarding the U.S. corporate stakes and the specific date of the request, other outlets provided more cautious framing. Both BTA and Utroruse reported the core facts of the request by James David Vance and the subsequent halt in strikes, but both outlets explicitly noted that the information could not be independently verified through other sources.
