In Defending the Watch Tower Society, the Governing Body says in JW.org:
Charity. We have provided material relief to those suffering from tragedies—whether man-made, such as the 1994 genocide in Rwanda, or natural, such as the 2010 earthquake in Haiti.

However, we know that this charity is not given to people who is not in the sect.
