TOKYO -- Nearly a third of oil tankers operated by Russia's largest maritime transport company were sailing without reported destinations at times since the invasion of Ukraine, in what analysts say shows the difficulty of enforcing Western sanctions on Moscow's energy exports.
State-run Sovcomflot lacked destination information for up to 24 of its 76 tankers at the same time in March and April, shows a Nikkei analysis of public data provided by MarineTraffic.
