"For the same reason sanctions agreed on by Russia, China and North Korea (also a group comprising several nations) would not mean "international sanctions"." You are saying that three nations are too few to be "international", and therefore nearly 30 must be too few also? My general rule of thumb is that an order of magnitude often makes a meaningful difference.
