British foreign secretary Philip Hammond has said that the West will impose more sanctions on Russia if separatist forces in Ukraine launch another offensive.
Russia’s economy has been hit badly by sanctions and the falling price of oil.
The Ukrainian government and separatists had begun to stick to a ceasefire agreed last month.
But the conflict in Ukraine will not be solved by the ceasefire, which only temporarily freezes the stand off and entrenches nationalist divisions. Imperialist rivalry between the West and Russia is tearing Ukraine apart. Only revolt from below can stop it.
