We report on a recent study of the Bsπ and BK¯ interactions in finite volume [1]. We show the discrete energy levels in two scenarios whether the coupled channel interactions are either strong enough to dynamically generate the X(5568) or too weak to produce it. Supplemented by the state of the art lattice QCD simulations, our study supports the picture that the interactions are weak and the X(5568) can not be a dominant Bsπ and BK¯ molecule.
