Stop aid, no. Never. I do however believe that how it is being spent ought to be reviewed, as giving it directly to a government, rather than a charity who is actually doing the work, is more likely to lead to corruption.
Having been to places where help is needed, just giving money to a government of a poor country isn't always the best thing to do. Aid to countries such as China is now pretty much pointless as they are a growing economic power who should be able to improve things on their own.
