  We evaluate a number of new instanton-induced phenomena in QCD, starting with
static dipole-dipole potentials, and proceeding to quark-quark and
dipole-dipole scattering at high energy. We use a non-perturbative formulation
of the scattering amplitude in terms of a correlator of two Wilson-lines
(quarks) or Wilson-loops (dipoles) and analyze the Euclidean amplitudes with
both perturbative gluons and instantons. The results are analytically continued
to Minkowski geometry, by interpreting the angle between the Wilson lines as
rapidity. We discuss the relevance of our results for the phenomenology of
near-forward hadronic processes at high energy, especially for processes with
multiple color exchanges.
