  Any quantization of a quasitriangular Lie bialgebra g gives rise to a
braiding of the dual Poisson-Lie formal group G^*. We show that this braiding
always coincides with the Weinstein-Xu braiding. We also define the lifts of
the classical r-matrix r as certain functions on G^* x G^*, prove their
existence and uniqueness using co-Hochschild cohomology arguments and show that
the lift can be expressed in terms of r by universal formulas.
