A scheme of 1 -> 2 optimal universal asymmetric quantum telecloning for pure multiqubit states is proposed. We first investigate the telecloning of arbitrary 2-qubit states and then extend it to the case of multiqubit system. We discuss the scheme in terms of the quantum channels and fidelities of clones, as well as the entanglement of states in the telecloning.
