Abelian Chern-Simons gauge theory is known to possess a `S-self-dual'
action where its coupling constant k is inverted {\it i.e.} k↔k1. Here a vector non-abelian duality is found in the
pure non-abelian Chern-Simons action at the classical level. The dimensional
reduction of the dual Chern-Simons action to two-dimensions constitutes a dual
Wess-Zumino-Witten action already given in the literature.Comment: 14+1 pages, LaTeX file, no figures, version to appear in Phys. Rev
