We consider the branching ratios and CP asymmetry in the B meson decays into two pseudoscalar mesons in the generalized factorization approximation. We also investigate the possible effects of the enhanced chromomagnetic interaction b --> s g on these exclusive B meson decays that was suggested as a possible solution to the semileptonic branching ratio of B mesons, the missing charm puzzle and the large B --> \eta^{'} + X_s. We finds that such enhanced b --> s g interaction degrades the agreement between the data and the model predictions for B meson decays into two light mesons in the generalized factorization approximation.
