Russia already pulled out of the nuclear test ban treaty, they have no leverage over the West getting "a free nuclear test" anymore, and anyway, all that the country doing the launch needs to do is show the trajectory estimation data. The only countries truly capable of something like this within the next couple of decades would be the US or China anyway. So only their opinion really matters and both of them would likely just complain for appearances but not actually seriously oppose the action. Anyone else doing the complaining is just looking for any excuse to pull out of the test ban treaty and should just be threatened with heavy sanctions if they do (as they would, even without a dangerous asteroid bearing down on Earth).
