We study the final state interaction effects in B\ensuremath→KK decays. We find that the t channel one-particle-exchange diagrams cannot enhance the branching ratios of B0\ensuremath→K0K0 and B^\ensuremath-\ensuremath→K0K^\ensuremath- very sizably. For the pure annihilation process B0\ensuremath→K+K^\ensuremath-, the obtained branching ratio by the final state interaction is at O(10^\ensuremath-8).
