Correa, however, appeared cool to Snowden an interview with the Guardian newspaper.
Asked whether he would like to meet Snowden, Correa was quoted as saying: "Not particularly. He's a very complicated person. Strictly speaking, Mr. Snowden spied for some time."
He was quoted as saying that Ecuador would not consider an asylum request until Snowden was on its territory and his government would not help him travel to Ecuador.
The expanded requests for asylum come as the Obama administration contends with European allies angry about the release of documents that alleged U.S. eavesdropping on European Union diplomats.
Obama said Monday that the U.S. would provide allies with information about new reports that the NSA had bugged EU offices in Washington, New York and Brussels. But he also suggested such activity by governments would hardly be unusual.
French President Francois Hollande said Tuesday that France has "not received any particular requests from Mr. Snowden." He also called for a common EU stance on the NSA snooping.
France prides itself on being a haven for political prisoners, and offers asylum to more people annually than any other country but the United States. French politicians on the far right and far left have called for France to take Snowden in — as have members of the Green party, which is a part of Hollande's Socialist-led government. However, it is unlikely that France would take in Snowden. Hollande and leading French officials, despite outraged comments in recent days, sees the US as a key ally.
A foreign ministry spokeswoman in Beijing said it was not aware of Snowden's possible plea to seek asylum in China.
