tate-owned energy firm Pertamina has denied importing Russian oil as the European Union reportedly considers unprecedented sanctions against Indonesia’s Karimun Port.

In a report on Feb. 4, Reuters cited ship-tracking data from Kpler and Vortexa indicating that Indonesia received two cargoes of Russian Sakhalin Blend crude oil, in December 2025 and January 2026.

The cargoes, each measuring approximately 700,000 barrels, were reportedly unloaded at the ports of Balikpapan and Cilacap.

Responding to the report, Pertamina official Milla Susilo, the former senior communications manager of refinery and petrochemical arm PT Kilang Pertamina Internasional (KPI), told The Jakarta Post: “Pertamina has not imported any Russian crude oil.”

Previously, Pertamina noted that all its oil imports were carried out in accordance with applicable regulations to secure national energy supplies.

Pertamina vice president of corporate communications Muhammad Baron said the firm was liaising with relevant subsidiaries to assess the accuracy of the circulating reports.
