Russia’s state run electric company said Thursday it has reduced the amount of power it sends to Belarus because of an outstanding debt.

Russia’s InterRao power provider lowered its to supply to Belarus to 200 megawatts, which is half of what it usually provides.

Belarus has owed Russia just over $48 million in unpaid electric payments since March.

Russia is threatening to cut all service to Belarus if the outstanding payments are not received by June 19th.

Russia supplies Belarus with ten percent of its power needs.
