With the help of the recent developments in the heavy quarkonium physics, we reexamine the long distance (LD) effects in B --> X(s)e(+)e(-) dominantly from the charmonium resonances J/Psi and Psi' through the decay chains B --> X(s)J/(Psi(Psi') --> X(s)e(+)e(-). We find that the resonance to nonresonance interference are reduced substantially. (C) 1998 Elsevier Science B.V.
