I agree the White Fang is likely international. That said, it is possible that not all the White Fang turned to violence and some of the branches from the other kingdoms didn't accept the new leader and his violent measures and, well, branched out to continue with their on their own locally.

There is also the possibility Blake isn't form Vale. For all we know, Adam and her might have been sent to Forever Fall to attack that train but be from somewhere else. So, when she took the decision to desert, she expected them to expect her to return to her native kingdom. Alternatively, if she is from Vale, she could have expected them to think she would try to run off somewhere else and not stay.

Also, if some of the non-Vale branches of the White Fang branched out when the leadership shifted, it is possible the new White Fang is centralized in Vale so, even if they are present in other kingdoms, they would be less powerful there and those safer for Tukson to go to Vacuo.
