Biden and Scholz met in private in the Oval Office for over an hour, a senior administration official said.
Sitting next to Scholz in the Oval Office, Biden thanked the German leader for his "strong and steady leadership" and support for Ukraine.
Speaking before the meeting, U.S. officials said discussion points included the state of the war and how to respond if China provided military aid to Russia.
"Every step China takes toward Russia makes it harder for China with Europe and other countries around the world."
Biden hailed Scholz's decision to sharply increase Germany's military spending and diversify energy sources away from Russia, and said the two leaders had worked in lockstep with other allies to support Ukraine.
