Russia’s seaborne crude exports continue to flow while European Union nations wrangle over sanctions to block purchases and make it harder for the country to ship its barrels elsewhere.

Shipments of the nation’s crude were little changed in the seven days to Friday compared with the previous week, even as the volume sent to Asia from Russia’s western ports tumbled.

A total of 34 tankers loaded about 24.9 million barrels from Russian export terminals, according to vessel-tracking data and port agent reports. That put average seaborne crude flows at 3.56 million barrels a day, down by about 2% against a revised 3.62 million barrels a day in the week ended April 29.
