"regrettable", would be the more appropriate word.
I would just say China disapproves of its weapons being used against innocent civilians and leave it there.
At end of the day, the people using the weapons bare full responsibility for their own actions.
Or does anyone seriously think they would all be holding hands and singing without ‘evil’ Chinese advanced weapons, instead of beating each other to death with rocks and stones if that was all they had to hand?
