BERLIN (AFP) - German Chancellor Angela Merkel called on Sunday for European Union-wide data protection rules and transparency from Internet giants such as Google and Facebook, reacting to reports of sweeping United States online surveillance.
In discussions on a European privacy protection agreement, Germany would urge "that the companies here in Europe tell us whom they are giving the data to", she said, vowing that Berlin would take "a very firm stance" on the issue.
The conservative chancellor, who faces elections on September 22, told ARD public television that "internationally, we should also negotiate an agreement" and that "it would of course be good if Europe spoke with one voice".
While in Germany "we have a great federal privacy laws", this did not protect online users, Dr Merkel said.
Because the European operations of Facebook are registered in Ireland, they are subject to Irish law, Dr Merkel said, adding that "therefore we do need a unified European solution".
She demanded that "Internet companies such as Facebook, Google and others inform European countries whom they are handing the data to".
Dr Merkel had last week defended the role of secret services in keeping citizens safe and praised the decades-old US-German security partnership.
The issue of state snooping is especially sensitive in Germany, which has dark memories of secret police activities under the Nazi and East German communist regimes.
In the election battle, her Social Democratic rival Peer Steinbrueck charged at the weekend that Dr Merkel had breached her oath of office in which she vowed to protect German citizens, amid the US surveillance of their emails, web searches and telephone data.
Dr Merkel, who has stressed the need to find a balance between security and freedom, said in the ARD interview: "What is reasonable? We are working together against terrorism, but on the other hand the protection of citizens' data must be ensured." The chancellor said she had spoken to her interior minister Hans-Peter Friedrich, after he returned from a fact-finding trip to Washington on the online surveillance reported by fugitive former intelligence contractor Edward Snowden.
She said minister Friedrich had been informed that German companies had not been targeted.
"The interior minister was told very clearly there is no industrial espionage against German companies," Dr Merkel said.
