We report on recent measurements of flavor-changing-neutral-current b → s transitions at Belle experiment. Lepton universality tests using B → K ( * ) l + l − and measurements of the CP asymmetry difference (∆A CP ) and isospin asymmetry (∆ 0− ) using sum of exclusive B → X s γ are reviewed. All of the measurements are performed on the full 711 f b −1 data sample recorded by the Belle experiment at the ϒ(4S) resonance.
