N2 - We study Bs → KK decays in the framework of the PQCD. We show that the branching ratios of Bs → (K+K-, K0K̄0) are about (22.43, 25.78) × 10-6 for φ3(γ) ≃ 72°, which are consistent with the model-independent estimations. We find that the typical scale of the decays is near 1.7 GeV. We also point out that the induced strong phase δ is around 207° so that the direct CP asymmetry of Bs → K+K- could reach 15%.
