Swiss President Ueli Maurer said in comments broadcast today that he was outraged at revelations of sweeping US surveillance on allies, insisting the snooping would weaken rather than strengthen Washington.
"One cannot conduct surveillance and spy on one's friends. That is how you disrupt confidence between states," he told Swiss public broadcaster SRF.
"Even if you are big and powerful, you cannot sit on those who are smaller than you and bug their phones," he said. "In the end, this will not strengthen the United States. Quite the opposite, it weakens the country."
His comments came amid mounting global outrage over reports of widespread US spying on foreign citizens, as well as on a number of world leaders, including German Chancellor Angela Merkel.
"Freedom is a fundamental value. To spy on either politicians or citizens is not ok. It is not part of our culture," Maurer said.
Switzerland had no immediate plans to react officially to the allegations that Merkel's mobile phone had been tapped, he added.
"We are still studying what may have happened here and how we should react.
