A stand-off between the two countries had threatened to disrupt supplies to Europe when the existing contract expires on December 31.
...Late on Thursday, Russian energy minister Alexander Novak and his Ukrainian counterpart Oleksiy Orzhel said they had struck an agreement in principle for a new contract, adding that talks were set to continue in Minsk on Friday.
