We present a Newton-type hybrid proximal extragradient primal-dual interior point method for solving smooth monotone mixed complementarity problems. Dual variables for the nonnegativity constraints are introduced. The ergodic complexity of the method is O(1/k(3/2)). The method performs two types of iterations: underelaxed hybrid proximal extragradient iterations and short-steps primal-dual interior point iterations.
