  We analyze the charm quark electric dipole moment (EDM) in the minimal
supersymmetric extension of the standard model (MSSM), including important
two-loop gluino contributions. Considering the experimental constraint on the
neutron EDM, the theoretical prediction for the charm quark EDM can reach about
$10^{-20}e\cdot cm$. If taking into account the mixing between the scharm and
stop quarks in the effective supersymmetry scenario, the charm quark EDM can be
enhanced to $\sim 10^{-19}e\cdot cm$. Direct production of the CP-odd $^1P_1$
state $h_c$ in $e^+e^-$ annihilation via the CP-violating process at the
BES-III and CLEO-C is analyzed.
