Brasilia, January 31 (RHC) -- Brazil's Foreign Minister Luiz Alberto Figueiredo said Thursday that his meeting with a leading U.S. official over U.S. spying on Brazil failed to resolve the matter.

The Brazilian diplomat met Thursday with U.S. National Security Advisor Susan Rice in Washington, but said later the talks failed to put the matter to rest, Xinhua news agency reports.

The minister said his meeting with Rice did not signify a permanent solution to the tension between the two countries caused by revelations that U.S. intelligence agencies spied on Brazilian President Dilma Rousseff, government officials and companies.

Figueiredo said, however, that the dialogue between the two sides will continue.  During the talks, Rice presented her government's defense of its espionage scheme, said Figueiredo, adding those explanations now need to be relayed to Rousseff.  Figueirdo said that the U.S. did not provide all the clarifications that the Brazilian government required.

Washington's rampant spying, which also reportedly targeted German Chancellor Angela Merkel and other world leaders, has rattled Brazil-U.S. relations, and prompted Rousseff to cancel a state visit to Washington D.C. last year.

Rousseff also denounced the spying before the United Nations General Assembly and has called for regulations to protect individual privacy.
