The Chinese ambassador in Berlin has been summoned for urgent talks about media reports that Russian soldiers were being trained in China, the German foreign ministry said on Friday. These “deeply disturbing” reports point to support for Russia from Chinese state actors, in particular the Chinese People’s Liberation Army, it said. “Anything that enables Russia to continue its war of aggression against Ukraine also represents a threat to our security,” the ministry said. On 20 May, the German daily Die Welt reported that the Chinese army had secretly trained several hundred Russian soldiers on its territory, some of whom had been deployed in Ukraine, citing classified documents from European intelligence services.

Russia’s ⁠Defence Ministry claimed ⁠on ⁠Friday its ​forces had “completely” taken ⁠control of Kostiantynivka in eastern Ukraine, ⁠whose capture Moscow ‌has long sought in its advance through Donetsk ‌region. The battle for this city, which had about 78,000 inhabitants before the war, has been taking place since late 2025 and now constitutes the main Russian effort on a front more than 1,000km long. “The city is now entirely under our control,” Kremlin spokesperson Dmitry Peskov told reporters. There was no independent verification of the claim.
