German Chancellor Olaf Scholz has warned that the ongoing Russian war against Ukraine risks damaging the "entire international order."

Scholz said the war and "Russia's rearmament" violated "a principle of the United Nations Charter, the principle of the inviolability of state borders."

The comments came at the beginning of his meeting with Xi. Scholz also spoke about how important it was that China and Germany cooperate on climate change action.

Germany's chancellor spoke of the danger posed by nuclear escalation as well. "It is clear, we both made it clear at our last meetings here in Beijing, that the use of nuclear weapons should not even be threatened," he said.

"I would like to discuss with you today how we can contribute more to a just peace in Ukraine."

Ahead of Scholz's visit, Washington accused China of massively supporting the Russian arms sector.
