This isn't a game where you win if you "damage" your "opponent" a certain degree. Individuals, countries, have goals they are trying to actualize. Accusations are made if the accuser believes it will serve them. Throwing unprovable accusations at China helps with nothing western countries are trying to accomplish. The most you can get out of it is some points during an election - it is helpful in painting a bogeyman draped in Chinese colors. Even if the goal was to reach an international treaty banning such research, it would make no sense to alienate China this way. It would put China in a position where they could not sign such a treaty without appearing weak during a time in which they are putting a lot of effort in appearing strong.
