The head of NATO has told the BBC that China should face consequences for supporting Russia's war in Ukraine, if it does not change its ways, the BBC reported. Jens Stoltenberg said Beijing was "trying to get it both ways" by supporting Russia's war effort, while also trying to maintain relationships with European allies. "This cannot work in the long run," Stoltenberg told BBC News during a visit to Washington. A peace summit held in Switzerland at the weekend saw dozens of nations commit to supporting Kyiv, but Russia called it a waste of time and said it would only agree to peace talks if Ukraine essentially surrendered. When pressed on what NATO members might do about China's support of Russia, Stoltenberg said there was an "ongoing conversation" about possible sanctions. He said China was "sharing a lot of technologies, [like] micro-electronics, which are key for Russia to build missiles, weapons they use against Ukraine." He added that "at some stage, we should consider some kind of economic cost if China doesn't change their behavior." Beijing is already under some sanctions for its support of Russia—last month, the US announced restrictions that would target about 20 firms based in China and Hong Kong. China has defended its business with Moscow, saying it is not selling lethal arms and "prudently handles the export of dual-use items in accordance with laws and regulations."
