Let $ \mathfrak{g} $ be a quasitriangular Lie bialgebra over a field $ K $ ofcharacteristic zero, and let $ \mathfrak{g}^* $ be its dual Lie bialgebra. Weprove that the formal Poisson group $ K\big[\big[\mathfrak{g}^*\big]\big] $ isa braided Hopf algebra, thus generalizing a result due to Reshetikhin (in thecase $ \, \mathfrak{g} = \mathfrak{sl}(2,K) \, $). The proof is via quantumgroups, using the existence of a quasitriangular quantization of $\mathfrak{g}^* $, as well as the fact that this one provides also aquantization of $ K\big[\big[\mathfrak{g}^*\big]\big] \, $.
