We study spontaneous CP violation in association with so-called SUSY flavor problem, SUSY CP problem, and stability of electroweak (EW) scale on the context of supersymmetric grand unified theory (SUSY GUT). In view of naturalness we retain stop masses on EW scale. Then in order to suppress non-decoupling SUSY contribution to up quark EDM we examine a certain type of flavor structure where up-type quark sector is real whereas down-type quark and charged lepton sectors are complex. We exhibit, as an example, an explicit model based on E{sub 6} SUSY GUT with SU(2) flavor symmetry that realizes these situations.
