  We show that the action of universal $R$-matrix of affine $U_qsl_2$ quantum
algebra, when $q$ is a root of unity, can be renormalized by some scalar factor
to give a well defined nonsingular expression, satisfying Yang-Baxter equation.
It reduced to intertwining operators of all representations, corresponding to
Chiral Potts, if the parameters of these representations lie on well known
algebraic curve. We also show that affine $U_qsl_2$ for $q$ is a root of unity
form the autoquasitriangular Hopf algebra in the sence of Reshetikhin.
