Yesterday's decision to demand the departure of the intelligence representative at the US Embassy in Berlin was "the right decision, a necessary step and an appropriate reaction to the breach of trust that has taken place," Foreign Minister Frank-Walter Steinmeier told reporters in Berlin.
It followed reports over the past 10 days that US intelligence had recruited two Germans, a man who worked at the country's foreign intelligence agency and a defence ministry employee. Steinmeier said those reports were "troubling."
Steinmeier said he will meet Kerry on the sidelines of talks in Vienna about Iran's nuclear program.
There is "no alternative" to Germany's longstanding partnership with the United States in view of challenges in Ukraine, Iran, Afghanistan and elsewhere, Steinmeier stressed.
"That is why this cooperation must be marked not just by trust but by mutual respect."
"We want to reinvigorate our partnership, our friendship on an honest basis, we in any case are prepared to do that," he said. "And that will be the message I will give to my American colleague.
