Washington: The US and Britain have decided to continue their sanctions on Russia until it ends its "aggression" in Ukraine, saying the Moscow has chosen to tear up the international rulebook in Europe and trampled over the affairs of a sovereign state.
"We agree on the need to maintain strong sanctions against Russia until it ends its aggression in Ukraine, and on the need to support Ukraine as it implements important economic and democratic reforms," Obama told reporters at a joint White House news conference with visiting British Prime Minister David Cameron.
Cameron said in Europe, Russia had chosen to tear up the international rulebook and trample over the affairs of a sovereign state.
"This threatens our stability and our prosperity. It is important that every country understands that, and that no one in Europe forgets our history. We cannot walk on by," he said.
"So we will continue to put pressure on Russia to resolve this crisis diplomatically, and at the same time, we will continue our efforts to support Ukraine on the path of reform, including with financial assistance," Cameron said.
"We also reaffirmed our obligations as NATO partners to stand by our allies, and we'll be contributing an additional thousand troops for exercises in Eastern Europe this year," he said.
