We have numerically studied the interaction of in-phase and out-of-phase bright solitons in nematic liquid crystals with competing nonlinearities. In particular, we propose the nonlocality management technique to steer the beam interaction in nematic liquid crystals with competing nonlinearities. By controlling the degree of nonlocality of the material, three methods of regulating the degree of nonlocality were proposed to control soliton interactions. It was found that out-of-phase soliton pairs exhibit approximately adiabatic propagation under cosine function type regression control. To our knowledge, this is the first observation of adiabatic propagation of out-of-phase soliton pairs in nonlocal media with competing nonlinearities. Controlling soliton interactions by regulating the degree of nonlocality may provide theoretical guidance for the experimental realization of all-optical interconnections and all-optical devices.
