Since taking office in January, Trump has resisted pulling the plug on the deal though he continues to threaten to do so.
Germany is one of the few Western democracies with an embassy in Pyongyang. It has been pushing for peaceful solutions to ease tensions along the Korean peninsula and slammed Trump's more bombastic rhetoric regarding the North's rapidly developing nuclear program.
Meanwhile, Italy has announced it will expel North Korea's ambassador in protest against Pyongyang's developing nuclear program, according to Italian Foreign Minister Angelino Alfano.
"The ambassador will have to leave Italy," Alfano said. "We want to impress on Pyongyang that isolation is inevitable if they don't change tack."
The minister added that Madrid has declared the North Korean ambassador to Spain "persona non grata," while Portugal had broken off diplomatic ties with Pyongyang altogether.
