In order to explore non-local effects in the CDW depinning in the blue bronze K0.30MoO3, we have studied the influence of longitudinal dc current Idc flowing in the vicinity of the bottom surface of the sample on the threshold field Et.p measured on the top surface with unipolar rectangular current pulses Ip flowing through the bulk of the sample. When Idc and Ip have the same (resp. opposite) sense. Et.p decreases (resp. increases) with Idc. In both cases. the excess CDW current ICDW depends on Idc and obeys a power law: ICDW α [Vp-Vt,,p(Idc)]β with an exponent β -1.3 which does not change with Idc..
