U.S. Secretary of State Marco Rubio and Kazakh Foreign Minister Yermek Kosherbayev discussed the security of the Caspian Pipeline Consortium (CPC) in a July 29 phone call, underscoring the importance of uninterrupted Kazakh oil exports after recent attacks on tankers temporarily halted supplies. The call came ahead of President Kassym-Jomart Tokayev’s planned visit to Washington, even as the U.S. Senate advanced new sanctions against Russia.
Pipeline Security Discussion
Rubio emphasized the strategic importance of reliable energy flows through the CPC, which carries roughly 80% of Kazakhstan’s oil exports to global markets. Exclusive.kz reported that the two sides discussed measures to ensure uninterrupted shipments after drone attacks on tankers in the Black Sea disrupted transshipments. The phone conversation also covered preparations for Tokayev’s upcoming trip to Washington, according to the Times of Central Asia.
Tanker Attacks and Supply Disruption
Recent strikes on oil tankers serving the CPC route caused temporary supply halts, raising concerns about the security of Kazakhstan’s main export artery. The CPC pipeline, operated by a consortium that includes U.S. giant Chevron, transports crude from western Kazakhstan to the Russian port of Novorossiysk. Following the attacks, Kazakh oil shipments via the Black Sea briefly dropped by an estimated 20%, according to industry data cited by Exclusive.kz.
U.S.-Kazakhstan Relations
The call occurred amid deepening U.S.-Kazakhstan engagement, with Tokayev’s visit expected to focus on energy cooperation and regional security. Meanwhile, the U.S. Senate on July 29 approved a procedural motion for a new sanctions package targeting Russia, a move that could complicate the transit of Kazakh oil through Russian territory. Kaktus Media noted the vote in its morning roundup of war-related developments.
What's Next
Both sides are expected to finalize details of Tokayev’s Washington trip in the coming weeks, though a specific date has not been announced. It remains unclear whether the new U.S. sanctions on Russia will affect the operation of the CPC or the broader energy partnership.
