A kinetic equation for a two-dimensional double-species point vortex system is obtained. The obtained collision term consisting of a diffusion term and a drift term has several physically good properties, for example, conserving a mean field energy and satisfying H theorem. It should be emphasized that the drift term plays an essential role for self-organization in a point vortex system with negative temperature.
