Germany and the United States will continue to closely coordinate their efforts to support Ukraine's army, German Defense Minister Boris Pistorius said on Wednesday.

The minister made his first official visit to Washington on Wednesday to meet with US Secretary of Defense Lloyd Austin and President Joe Biden's national security advisor, Jake Sullivan.

"We agree on all key issues," Pistorius told reporters after the meeting.

"Both of them have more than clearly underlined and repeatedly emphasized how much they appreciate the German commitment," Pistorius said.

"They know very well the scale we are on and that we are now the second-largest supporter of Ukraine. There was not a hint of criticism."

Meanwhile, the US praised Germany's contributions to the war effort, which includes a €2.7 billion ($2.95 billion) package that was announced in May.

"As Russia continues to direct this war of choice, I appreciate everything that Germany has done to strengthen Ukraine's capability," Austin said.

"Your security assistance and training contributions for Ukraine's defenders have been invaluable, and we must keep pushing hard to help Ukraine succeed."
