On Sunday, Reuters cited two oil traders as saying that Russia had begun curbing supplies to the domestic market by cutting the flows to two refineries, Naftan and Mozyr. In Ukraine last January, that was a first step toward a more general shutdown.  Russian officials took pains to emphasize that the export volumes would continue to flow, while either refusing to confirm or denying the report of a local shut-off in Belarus.

Belarus is one-half of a loose confederation with Russia that was supposed to eventually lead to a common currency and customs zone. Yet in the oil business, so vital to Russia’s economy, Belarus was treated with privilege but as less than a fully integrated partner. The government in Belarus posted a statement saying that they had been subjected to “unprecedented pressure” to acquiesce to Russia’s demands. Both sides, however, said Sunday that negotiations were continuing.

Last January, the Russian natural gas monopoly Gazprom first tried to halt supplies to Ukraine’s domestic market in a pricing dispute. It then shut down the pipeline entirely, accusing the Ukrainians of continuing to supply their own needs by siphoning gas intended for export.
