  A supersymmetric generalization of the Peccei-Quinn mechanism is proposed in
which two U(1) CP violating phases of the supersymmetric standard model are
promoted to dynamical variables. This amounts to postulating the existence of
spontaneously broken global symmetries in the supersymmetry breaking sector.
The vacuum can then relax near a CP conserving point. As a consequence the
strong CP and supersymmetric CP problems may be solved by similar mechanisms.
