Abstract	Current experimental measurements of the CP asymmetry (ACP ) in D0 -> K0s Ks0 decay are limited by the statistical precision, with the best measurement performed by Belle experiment using 921 fb−1 of data. Using D0->K^{+}K^{−} as a control mode reduces the uncertainty in ACP in addition to making the analysis simpler. In this work, we report the preliminary result of the measure-ment of the raw asymmetry (Araw) for the D0->K^{+}K^{−} decay using the Belle II simulations. The final goal of this analysis is to measure the ACP in D0->Ks0 Ks0 with D0->K^{+}K^{−} as a reference mode.
