There's a treaty that everyone signed, and it says Starlink launches are fine as long as the country they launch from says OK. China can OK Chinese launches. Satellites aren't supposed to interfere with each other, but that's not strictly defined. You aren't supposed to create debris, but the standard for that isn't strict at all. There's a good discussion going on about extending that treaty: stricter rules on deorbiting failed satellites and stages, light pollution, excessive numbers of satellites in narrow orbital bands, and so on.
