  Interaction of two solitons of the different polarities in the framework of
modified Korteweg-de Vries (mKdV) equation is studied. Three types of soliton
interaction are considered: exchange and overtaking for solitons of the same
polarity, and absorb-emit for solitons of different polarity. Features of
soliton interaction are studied in details. Since the interaction of solitons
is an elementary act of soliton turbulence, the moments of the wave field up to
fourth are studied, which are usually considered in the turbulence theory. It
is shown that in the case of interaction of solitons of the same polarity the
third and fourth moments of the wave field, which determine the coefficients of
skewness and kurtosis in the theory of turbulence, are reduced, while in the
case of interaction of solitons of different polarity these moments are
increased. The results are compared with the estimations for the two-soliton
interaction in the framework of the Korteweg - de Vries (KdV) equation.
