The State Department said that the talks would go ahead and the Snowden's case would be among the key issues raised when Secretary of State John Kerry and Defence Secretary Chuck Hagel will meet their Russian counterparts.

"We have raised the Snowden issue with Russian officials many times in recent weeks. We expect to do so again," State Department spokeswoman Jen Psaki told reporters.

"We would like to see Snowden’s return to United States. I don't know technically what that requires, but we know they have the capability to do that,” he added.

United States appears to be trying hard to avoid derailing ties with Russia by proceeding with some high-level talks with it.

Experts believe that the Snowden asylum issue is likely to have limited blow on the US-Russia ties. The two sides would not worsen relations below a certain level as US needs Russia more than Russia needs US, experts say. They have made the observation in the light of issues such as nuclear non-proliferation in Iran, the Syrian crisis settlement and others.

Snowden had spent more than five weeks in a Moscow airport while trying to find a country for asylum. US wanted Russia to return him so that he could face charges for leaking National Security Agency surveillance secrets to the media. But Moscow's rejection has prompted President Barack Obama to rethink whether to hold a summit in Moscow with Russian President Vladimir Putin next month.


Worsened ties between the United States and Russia could make it even more difficult for the two nations to arrange any kind of political solution in Syria, for example.

Moscow has supported President Bashar al-Assad in Syria's civil war even as Obama has led international calls for him to step aside. Psaki said Syria would be part of the conversation.

"We certainly have our share of disagreements with Russia over a number of issues. And I'm sure they will be part of the conversation, as well," Psaki said.

She added that Iran's nuclear program would also come up.

There are concerns in Washington that, given deepening tensions, Russia may break ranks with Western countries seeking to curb Tehran's nuclear ambitions through tough sanctions.

Russian Deputy Foreign Minister Sergei Ryabkov criticized perceived U.S. wobbling on the need for top-level contact between the two countries.

"The US administration questions further bilateral contact at the highest level (due to the situation with Snowden)," Ryabkov was quoted as saying by Interfax. "It seems to me that this is an utter distortion of reality. This is viewing the world through a distorted lens."
