Abstract:	We calculate the long distance contributions to K-->pi v (v) over bar, pi pi v (v) over bar, and K-->pi pi v (v) over bar modes within the framework of chiral perturbation theory. We find that these contributions to decay rates of K-->pi v (v) over bar and K-->pi pi v (v) over bar in the chiral logarithmic approximation are at least seven orders of magnitude suppressed relative to those from the short distance parts. The long distance effects in this class of decays are, therefore, negligible.
