Fugitive former U.S. spy agency contractor Edward Snowden was seeking asylum in Ecuador on Sunday after Hong Kong allowed his departure for Russia in a slap to Washington's efforts to extradite him on espionage charges.
In a major embarrassment for President Barack Obama, an aircraft thought to have carried Snowden landed in Moscow on Sunday, and the anti-secrecy group WikiLeaks said he was "bound for the Republic of Ecuador via a safe route for the purposes of asylum."
Earlier, Ecuadorean Foreign Minister Ricardo Patino, visiting Vietnam, tweeted: "The Government of Ecuador has received an asylum request from Edward J. #Snowden."
It was a blow to Obama's foreign policy goals of resetting ties with Russia and building a partnership with China. The leaders of both countries were willing to snub the American president in a month when each had held talks with Obama.
The United States continued efforts to prevent Snowden from gaining asylum. It warned Western Hemisphere nations that Snowden "should not be allowed to proceed in any further international travel, other than is necessary to return him to the United States," a State Department official said.
U.S. Senator Charles Schumer charged that Russian President Vladimir Putin likely knew and approved of Snowden's flight to Russia and predicted "serious consequences" for a U.S.-Russian relationship already strained over Syria and human rights.
"Putin always seems almost eager to stick a finger in the eye of the United States - whether it is Syria, Iran and now of course with Snowden," Schumer, a New York Democrat, told CNN's "State of the Union" program. He also saw "the hand of Beijing" in Hong Kong's decision to let Snowden leave the Chinese territory despite the U.S. extradition request.
Ecuador, which has been sheltering WikiLeaks' founder Julian Assange at its London embassy for the past year, once again took center stage in an international diplomatic saga over U.S. data secrecy.
Ecuador's ambassador to Russia, Patricio Alberto Chavez Zavala, told reporters at a Moscow airport hotel he would hold talks with Snowden and Sarah Harrison, a WikiLeaks representative.
Hours later, shortly after midnight (2000 GMT Sunday), the ambassador emerged from a business-class lounge near the hotel and refused to say whether he had met Snowden or make any other comment. Shortly before he appeared, a cart with three plates of salmon and a Starbucks bag were rolled into the lounge.
Snowden, who had worked at a U.S. National Security Agency facility in Hawaii, had been hiding in Hong Kong, the former British colony that returned to China in 1997, since leaking details about secret U.S. surveillance programs to news media.
U.S. authorities had said on Saturday they were optimistic Hong Kong would cooperate over Snowden.
U.S. authorities have charged Snowden with theft of federal government property, unauthorized communication of national defense information and wilful communication of classified communications intelligence to an unauthorized person, with the latter two charges falling under the U.S. Espionage Act.

A source at Russian airline Aeroflot said on Sunday that Snowden was booked on a flight scheduled to depart for Havana on Monday at 2:05 p.m. (1005 GMT) from the same Moscow airport where the flight from Hong Kong arrived, Sheremetyevo.
The chief of Cuba's International Press Center, Gustavo Machin, said he had no such information though pro-government bloggers heaped praise on Snowden and condemned U.S. spying activity.
Venezuela, Cuba and Ecuador are all members of the ALBA bloc, an alliance of leftist governments in Latin America that pride themselves on their "anti-imperialist" credentials.
