  We study the contribution of the squark flavor mixing from the $LR(RL)$
component of the squark mass matrices to the direct CP violation of the $b\to
s\gamma$ decay and the CP-violating asymmetry in the non-leptonic decays of $B$
mesons. The magnitude of the $LR(RL)$ component is constrained by the branching
ratio and the direct CP violation of $b\to s\gamma$. We predict the correlation
of the CP asymmetries among $A_{\text{CP}}^{b \to s \gamma}$,
$\mathcal{S}_{\phi K_S}$ and $\mathcal{S}_{\eta 'K^0}$ of the B decays. The
precise data of these CP violations will give us the crucial test for our
framework of the squark flavor mixing.
