According to Reuters, Ecuador said Thursday it was waiving favorable trade rights under a trade agreement with the U.S. In a dig at Washington, officials there also offered the U.S. $23 million in aid for "education about human rights." 

The moves were a signal that Ecuador was not considering its own U.S. benefits in weighing Snowden's asylum request. 

In Washington, some analysts have said the U.S. could use both its direct aid and the trade benefits as leverage against Ecuador. That's because in recent months, Ecuadorean officials have made trips to Washington, jockeying for preferential treatment for some of its country's key native products like frozen broccoli and fresh-cut roses.
