China’s support for Russia’s full-scale invasion of Ukraine through the provision of technology for missiles and other weaponry is a “major mistake,” U.S. Ambassador to Beijing Nicholas Burns said Wednesday. He said that despite its claims of neutrality, China has sided with Russia, providing a range of technologies. “We think it’s a major mistake to allow Chinese companies, by the thousands, to be sending so many components, technology components, microprocessors (and) nitrocellulose to Russia to reinforce and strengthen the defense industrial base of the Russian Federation for this brutal war,” Burns said.
