A top Russian diplomat says the United States' cancellation of a critical part of its European missile defense system plan doesn't mollify Moscow's opposition.

U.S. Defense Secretary Chuck Hagel last week announced that plans to place missile interceptors in Poland and possibly Romania are being abandoned and that interceptors would be placed in Alaska instead.

The interceptors were to be the final phase of a program that Russia contends aims to counter its own missiles. Washington says the system is meant to stop missiles from Iran and North Korea.

Russian Deputy Foreign Minister Sergei Ryabkov was quoted by the Kommersant newspaper Monday as saying that "We feel no euphoria in connection with what was announced by the U.S. defense secretary and we see no grounds for correcting our position."
