We have readjusted the {ital short}-range part of the Paris nucleon-antinucleon potential taking into account the new {ital p{bar p}} data, in particular those from the CERN Low-Energy Antiproton Ring. Discrepancies between results of our earlier version and experimental data on charge-exchange cross sections are removed. Moreover, a significant improvement of the fit to cross sections and especially polarization in elastic scattering is obtained. Our analysis shows that the low-energy {ital p{bar p}} data and the short-range {ital N{bar N}} interaction are strongly dependent on each other.
