Kazakhstan's Ministry of Foreign Affairs on November 30 expressed protest to Ukraine over the attack on the infrastructure of the international Caspian Pipeline Consortium (CPC) at the Novorossiysk seaport.

On the same day, Turkey's MFA expressed concern over strikes on oil tankers in the Black Sea.

Kazakhstan stated that it views the attack on CPC as "an action damaging bilateral relations" and expects Kyiv to "take effective measures to prevent similar incidents in the future." MFA representative Aibek Smadiyarov called this the third targeted "act of aggression" against an allegedly purely civilian facility. Astana emphasized its role as a "responsible participant in the global energy market" and the CPC's significance for the stability of the world energy system.

On November 29, CPC announced a halt in operations and the loss of one of its berths following a drone attack. The terminal handles over 1% of the world's oil.

Turkey's MFA, in turn, expressed concern over the November 28 attack on the Gambia-flagged tankers Kairos and Virat. "These incidents in our exclusive economic zone have created serious risks for navigation, life, property, and environmental safety in the region," said Turkish MFA spokesperson Öncü Keçeli. The ministry assured that it continues contacts with the parties to prevent "the spread of the war to the Black Sea and its escalation."
