BERLIN, April 29 (Xinhua) -- German Chancellor Friedrich Merz on Wednesday said his personal relationship with U.S. President Donald Trump remains good despite a recent exchange of sharp rhetoric regarding the war in Iran.

Speaking at a press conference in Berlin, Merz said he and Trump remain "on good speaking terms," adding that he simply had doubts from the beginning regarding the actions initiated with the war.

Merz called for a swift resolution to the conflicts in Iran as Germany and Europe are suffering considerably from the consequences of the conflicts.

Earlier this week, Merz criticized the United States for its "planless" military engagement in Iran, saying that the United States "is being humiliated by the Iranian leadership."

In response, Trump wrote on social media on Tuesday that Merz "doesn't know what he's talking about" and is indifferent to Iran's nuclear ambitions. ■
