US, EU, and UK pressure countries on ship oversight

The US, EU, and UK are pressuring Liberia, the Marshall Islands, and Panama to increase oversight of ships carrying their flags to prevent the transport of Russian oil sold above the $60 price cap. Nearly 40% of the 535 dark-fleet tankers have registered ownership via companies incorporated in the Marshall Islands. The goal is to tighten compliance on the cap and make it more expensive for Russia to move oil without using Western shipping services.
