Abstract. We discuss applications of the perturbative QCD approach in the exclusive non-leptonic two-body B-meson decays. We brie°y review its ingredients and some im-portant theoretical issues on the factorization approach. PQCD results are compatible with present experimental data for charmless B-meson decays. We predict the possibility of large direct CP asymmetry in B0! + ¡ (23 § 7%) and B0! K+ ¡ (¡17 § 5%). We also investigate the branching ratios, CP asymmetry and isospin symmetry breaking in radiative B! (K¤=) ° decays
