The effects of nonlocal interactions in rare B decays, B → Xsl+l- are investigated. We show the correlation between the branching ratio and the forward-backward asymmetry via two coefficients of the nonlocal interactions. This will certainly help us find any deviations from the standard model through the nonlocal interactions.
