Brazilian President Dilma Rousseff cancelled a state visit to the United States next month over revelations that the National Security Agency spied on her government.
Her decision is the latest fallout over the NSA's spying programs around the world.
"Given the proximity of the scheduled state visit to Washington and in the absence of a timely investigation … there aren't conditions for this trip to be made," Rousseff's office said in a statement. "The Brazilian government is confident that when the question is settled in an adequate manner, the state visit can quickly occur."
A White House statement said President Barack Obama has ordered a review of U.S. intelligence activities, but "the process would take several months to complete."
"The president has said that he understands and regrets the concerns disclosures of alleged US intelligence activities have generated in Brazil and made clear that he is committed to working together with President Rousseff and her government in diplomatic channels to move beyond this issue as a source of tension in our bilateral relationship," the statement read.
Meanwhile, some foreign analysts say the NSA surveillance programs and possible military action in Syria, raise questions about Obama's standing in the world.
