Belarus state oil company Belneftekhim's Russian oil supplies are running as normal to EU countries through Belarus, despite an oil pricing disagreement between Russia and Belarus.
Refineries in Belarus stopped receiving oil supplies from Russia after both countries failed to reach a consensus on 31 December 2009.
The disagreement has raised the spectre of another interruption in winter oil supplies for EU energy consumers, reports Reuters.
Belneftekhim said that Russian oil is flowing normally to Belarus through the Druzhba oil pipeline, which links Russian fields in West Siberia to EU customers.
Russia supplies nearly 20% of Europe's gas via Belarus and Ukraine, and huge quantities of Russian oil flow through pipelines via both former Soviet states.
