Russia and the United States have completed the largest spy exchange since the Cold War.On Friday, at an airport in Vienna, Austria, an American plane and a Russian plane landed, parked side by side and exchanged occupants

The United States freed ten admitted Russian agents.The men and women were arrested in late June and pleaded(承认) guilty on Thursday.

In exchange, Russia freed four Russians serving prison sentences on charges of spying for the West.The men include Igor Sutyagin, an armed researcher who always denied the charges.Some considered him a political prisoner.

The United States deported(驱逐) nine Russian and an American citizen born in Peru.Some raised children while living quiet lives as married couples.

Russia’s Foreign Ministry praised the exchange, saying, “The action improved Russian-U.S.relations.”

The group was accused of trying to gain information on American nuclear weapons, foreign policy and politics for the SVR — Russia’s foreign intelligence service.

The ten were only charged with plotting(阴谋) to act as undeclared foreign agents.They were not charged with the more serious crime of spying, so the extent(程度) of their success as spies is not clear.

One of the Russians, Anna Chapman, drew attention with her looks and stories of her New York party life.Hr lawyer, Robert Baum, said she had not passed secret information to Russia or received any payment.He also said, “She was accused of communicating with a Russian official through a laptop to laptop communication, without the government specifying the nature of the communication.”
