As a currency depreciates, it weakens the purchasing power of that country...including its importers. So the general trend is a decline in imports.
The opposite happens for foreign importers...their currency now stands stronger comparatively...and hence the general trend is that exports of the country whose money got depreciated, increase.
Of course I could be wrong since I'm no expert and only going off of general trends. Could u perhaps shed more light on why the general trend wouldn't happen in this case?
