Kites fly because of the aerodynamic forces of lift and drag. The difference in air pressure on the top and bottom of the kite creates lift. The drag is created by the friction of the air flowing around the kite. The lift balances the weight of the kite. The thrust is created by the wind blowing on the kite.
To get the kite airborne, you need to provide it with enough lift to counteract its weight. Although numerous factors (e.g., the shape of the kite, its motion in the air, quality of air, etc.) affect the amount of lift produced in a kite, the principal contributor is the velocity of air that goes by the kite. The design of the kites helps, too; if you notice, they are made of a very light (but rigid) material and have minimal accessories (in the form of thin, wooden spokes) attached to them. Their shape is also streamlined (with a pointed leading corner) to help them split the oncoming air.
