  A new approach is proposed to describe the parity violation in the process of
scattering of a polarized proton by a proton at high energies. It is shown that
in the tree approximation the P-odd amplitude of proton-proton scattering is
substantially smaller than the P-odd amplitude in proton-neutron scattering.
The main source of P-odd asymmetry in proton-proton scattering is radiative
corrections due to the charge-exchange strong interaction. We predict that the
asymmetry in the inelastic cross section is substantially less than the
asymmetry in the elastic cross section.
