Washington: The Obama Administration dismissed the notion that Russia and China pose a major challenge to the United States.

"Clearly China and Russia do not represent our biggest adversaries in the world today, or the nations that we perceive to pose the greatest threat in terms of their intent to harm US interests," Deputy Nations Security Advisor Ben Rhodes said.

"We obviously spend a lot of time focused on, as a non-state actor, al Qaeda, but then nations like North Korea and Iran that pose a challenge to US interests," he said in response to question.

In terms of pure capability, obviously China and Russia are nations with large nuclear arsenals and large armies.

"But we have pursued a policy from the beginning of this administration of building cooperative relationships with the Chinese and the Russians and, frankly, those efforts have yielded concrete benefits that have served US interests as well as Chinese and Russian interests," he argued.

"Indeed, these conversations, we have pursued these great power relationship strategies in a very intensive way, not just through kind of periodic summits every six months or year, but we have now had nine face-to-face meetings with Hu Jintao. Vice President Biden met with Prime Minister Putin today in Moscow as part of our ongoing efforts to work on areas of common concern with the Russians," he said.
