Seeking to keep the trade talks on track, President Obama and Chancellor Angela Merkel of Germany later responded with an agreement that security officials from their countries would hold a “high-level meeting” in coming days, Ms. Merkel’s spokesman said in a statement.

In a telephone call to President Obama on Wednesday evening, the chancellor noted that a visit to Washington by senior officials from the German government and its intelligence services offered the chance for an “intensive discussion” of concerns over the scope of American intelligence activities, data protection and privacy, the statement said.

But French officials, speaking to reporters, made it clear that they would still favor delaying trade talks if there was no movement from the Americans on the espionage by next week.

And now, the uproar has encompassed Latin America as well.

“In some sense, it parallels ironically what the N.S.A. is doing,” said Faiza Patel, a co-director of the liberty and national security program of the Brennan Center for Justice at New York University School of Law, a research and advocacy organization. “The N.S.A. is reaching its tentacles aross the world.”

Mr. Snowden and his disclosures have touched different chords in each region. In Europe, Ms. Patel noted, they have provoked memories of the police states created by fascism and communism, with their heavy-handed surveillance of their own people. In Latin America, she said, they have touched on a wellspring of resentment over the legacy of colonialism and American power, as well as the region’s own history of secretive dictatorships.

The latest burst of outrage came in response to the diversion of a plane carrying Bolivia’s president, Evo Morales, as he was flying home from Moscow on Tuesday. He had attended a meeting of nations that export natural gas and had told Russian television that he was open to giving asylum to Mr. Snowden.
