Europe may be forced to review its long-term energy supply deals with Russia if the stand-off between it and Ukrainian separatists persists.
That view was expressed by German Chancellor Angela Merkel yesterday.
At the same time, she stressed that it was in Russia and the rest of the European Union’s interests to stick to their existing energy supply agreements.
"It's in the interest of both sides to co-operate," Ms Merkel said at a press conference during an official visit to Germany by the Finnish Prime Minister Alexander Stubb.
She pointed out that, whereas 38 per cent of her country’s gas was supplied by Russia, some European countries were entirely dependent on it for their supplies.
But she also said that energy policies may need to change in the medium and long-term “if there is a continued violation of basic principles”.
Ms Merkel concluded that “there is currently no way to remove” the EU’s existing sanctions on Russia, but the bloc would “continue the pressure within a reasonable political process.”
