German Chancellor Olaf Scholz told parliament on Wednesday that any violation of Ukraine's territorial integrity by Russia would come at a high price, although no further details were provided.

"The security situation on the Russian-Ukrainian border concerns us greatly," Scholz told the Bundestag lower house of parliament.

"Any violation of territorial integrity will have a high cost, and we will speak with one voice here with our European colleagues and transatlantic allies," he said, adding that he still wanted to talk to Russia.

“All EU member states are dedicated to the rule of law, and Germany stands with the EU Commission on this issue,” he said. “The EU will not be split by Russia. I still want discussions with Russia when feasible.”

Other key statements from his speech on separate topics include “we will not turn a blind eye to human rights violations in China.” and “the German-US relationship and NATO are non-negotiable security guarantees.”
