True, while it will certainly remove moisture from the air that would necessarily have fallen elsewhere, it's difficult to say whether or not it would cause measurable decreases in rainfall in places that would notice it. For example, we know that reforestation actually increases precipitation downwind, as trees draw water out of the Earth, which then evaporates out of their leaves. However, a nation that's seeding clouds isn't going to be doing it because they're trying to create rainforests, they'll be doing it because they want agriculture and clean drinking water, and it's unclear whether or not that can possibly give more than it takes from downwind neighbors.
