   <hidden TTP98-01  Coulomb resummation for b{\bar b} system near threshold and precision determination of \alpha_s and m_b. > We analyze sum rules for
 the \Upsilon system with resummation of threshold effects on the
 basis of the nonrelativistic Coulomb approximation.
 We found the pole mass of the bottom quark m_b=4.75 \pm 0.04 GeV
 and the strong coupling constant \alpha_s(M_Z)=0.118 \pm 0.006.
 The origin of the contradiction between two recent estimates
 obtained within the same formal framework is clarified.
