The European Union's incoming foreign affairs head Federica Mogherini said that the Russian "bear" needed to be handled with a mixture of firmness and tact.
Ukraine said it had struck a gas deliveries deal with Norway's energy giant Statoil aimed at helping it avert the consequences of a cut in Russian supplies.
President of Kazakhstan said that traditional energy was not possible to replace with alternative sources, which is why Kazakhstan should not be afraid of that its economy is based on raw materials.
Gasoline prices in Kazakhstan are substantially lower than those of the neighbouring Russia. They will be gradually growing until they match the Russian prices by 2019.
