French President Francois Hollande, speaking alongside his US counterpart Barack Obama, said Tuesday that the two allies had resolved their differences over American digital eavesdropping.

Leaders from many US allies, including Germany's Chancellor Angel Merkel, were angered by intelligence leaker Edward Snowden's revelation that the United States monitors their telephone calls.

But it is not known if Hollande's own telephone was tapped, and France has been more cautious in its critique, emphasizing the importance of its intelligence cooperation with Washington.

"We wanted to fight against terrorism, but we also wanted to meet a number of principles. And we are making headway in this cooperation. Mutual trust has been restored," Hollande said.

Hollande has not allowed concern over US spying to darken the mood of a much-anticipated state visit to Washington, but he did reiterate European concerns about data privacy in the Internet age.

"Mutual trust must be based on respect for each other's country, but also based on the protection of private life, of personal data," he said, during a joint White House news conference.
