  In the framework of perturbative QCD, double inclusive cross sections for
high $p_t$ parton production in nucleus-nucleus collisions are computed with
multiple rescattering taken into account. The induced long-range correlations
between numbers of jets at forward and backward rapidities are found to reach
$10\div 20$% for light nuclei at $\sqrt{s}=200$ GeV/c and to be suppressed for
heavy nuclei and LHC energies.
