Expression of the nucleon-nucleon interaction to leading order in 1/N
C
in terms of Fermi invariants allows a dynamical interpretation of the interaction and a consistent construction of the associated interaction currents. The numerically significant components of 4 different modern realistic phenomenological interaction models admit very similar meson exchange interpretations in the large-N
C
limit. The ratio of the volume integrals of the leading, next-to-leading and next-to-next leading-order terms in these interaction models is roughly 
, which corresponds fairly well to the ratios of 1/N

C
expansion if N
