Nope. The Outer Space Treaty forbids many things, but does not forbid anti-satellite weapons, especially if those weapons are not based on orbit. In fact, the Outer Space Treaty does not even forbid conventional weapons in orbit. It basically only bans WMDs in space, and forbids military use of other celestial bodies (nothing about space itself). Anti-satellite weapons were largely held in check by technical issues, cost, as well as avoiding escalation/arms race. The recent weapons test are an example of that. Once you start actively developing these weapons again, everyone else who can will follow to protect their interests. Both of their spins are largely for PR, not legal/treaty reasons.
