Prime Minister David Cameron has said Britain is ready to impose further sanctions on Russia if Moscow does not stop acting illegally in eastern Ukraine. Mr. Cameron accused Russia of reaping up the international rule book by stabilizing a sovereignty state but said Britain was not seeking another cold war. He said he would be speaking with president Putin at the G20 summit in Australia this weekend.

Mikhail Gorbachev has warned that we are on the brink of a new cold war. That is not an outcome we believe to be inevitable and neither it is one that we seek. And I will make that clear to president Putin in Brisbane this weekend. But I will also be clear that if Russia continues on its current path, then we will keep up the pressure and Russia’s relationship with the rest of the world will be radically different in the future.
