A picture of nuclear interactions at high energies (p(Lab) greater-than-or-equal-to 100 GeV/c) is proposed, where the only essential difference between nucleon-neucleon and central nucleus-nucleus collisions is the size of the interaction zone. In both cases intermediate multi-parton systems are created, which achieve thermodynamical equilibrium with respect to characteristics of light quarks and gluons. The characteristics of heavier quarks are far from equilibrium ones in nucleon-nucleon collisions, but the degree of equilibration is substantially increased in central heavy-ion collisions. Therefore, the multi-parton systems produced in central nucleus-nucleus interactions can manifest themselves as the quark-gluon plasma. A simple model based on this picture is formulated and confronted with the experimental data concerning J/psi suppression and strangeness yield enhancement, both revealed recently in central nucleus-nucleus collisions.
