Belarusian state petrochemical concern Belneftekhim plans to partially resume the export of Belarusian oil by the end of June. The suspension was caused due to problems with the oil pipeline system Druzhba. In April Belneftekhim registered a massive decrease in the quality of the Russian oil mixture coming via the oil pipeline system Druzhba. Both Belarusian oil refineries – Naftan and Mozyr Oil Refinery – were forced to reduce their workload and have suffered financial losses.
