Ukraine has agreed to halt attacks on non-Russian oil tankers and maritime infrastructure vital to Kazakhstan’s oil exports in the Black Sea following US intervention.

The US-brokered agreement comes after a series of Ukrainian drone strikes in July near the Caspian Pipeline Consortium (CPC) terminal in Novorossiysk, Russia, temporarily halted oil loadings and disrupted global energy markets, Kyiv Post reported.

According to an unnamed US official cited by Bloomberg, Ukraine committed to refraining from attacking CPC infrastructure and non-Russian vessels heading to the terminal.

The agreement stipulates that protected vessels must not be under Ukrainian sanctions, must not carry Russian oil or other cargo, and cannot be owned by Russian entities.

To facilitate the arrangement, Kyiv has established dedicated contact points to exchange information with commercial carriers and provide safe passage instructions.

The diplomatic push to protect the transit route was driven by heavy lobbying from the US oil industry.

In late July, the Trump administration warned Kyiv to cease attacks on non-Russian shipping after Chevron CEO Mike Wirth met with senior US officials.

The warning followed a Ukrainian strike that affected four tankers near Novorossiysk, one of which was chartered by the American energy giant.

Chevron holds a 15% stake in the CPC, which transports crude from Kazakhstan to the Black Sea, and a 50% interest in Kazakhstan’s highly productive Tengiz oil field. The July disruptions at the Novorossiysk terminal bottlenecked exports and forced Kazakhstan to throttle domestic oil production due to limited storage capacity.
