As odious as that technology is, as far as I know China is a major supplier of surveillance technology to the world's authoritarian governments. Belt and Road is an international infrastructure investment (and direct construction) project, not sure how its related to technology. It's also no different from all other nations' international aid programs, in that it both helps the receiving nation and makes them indebted to the originator.
