  A braided tensor category $FM_{\kappa}$ of `factorizable D-modules' over
configuration spaces is introduced, analogous to the category $FS_q$ of
factorizable sheaves from q-alg/9604001. This category is equivalent to the
category of finite dimensional representations of a complex semisimple Lie
algebra $\frak{g}$, with the Drinfeld's Knizhnik-Zamolodchikov tensor product.
This description, together with the result of op.cit., gives a new,
"Riemann-Hilbert" proof of the Drinfeld's theorem establishing an equivalence
of the above tensor category with the category of finite dimensional
$U_q\frak{g}$-modules ($q=\exp(2\pi i/kappa)$, $\kappa$ irrational).
