We present a new mechanism for B± → η′K±, and analyze it strictly within perturbative QCD. We find that such a new mechanism may dominate non-leptonic B-decays to light mesons. Within a reasonable parameter space, our prediction is in good agreement with the recent CLEO data on B± → η′K±. We conclude that there is no room for an abnormally large b → sg vertex from physics beyond the Standard Model.
