President Vladimir Putin has ordered officials to consider a possible reduction in Russian oil output to handle a decline in crude exports due to the dispute with Belarus.
German Chancellor Angela Merkel has warned that the interruption of Russian supplies westward "destroys trust," and said she will raise the issue when she meets with Putin on January 21.

The halt of Russian shipments is reported to have affected supplies in countries including Ukraine and EU members Poland, Hungary, Slovakia, the Czech Republic, and Germany.
