In this article, we calculate the nonfactorizable soft contributions in the B\ensuremath→\ensuremathηcK,\ensuremathχc0K decays with the light-cone QCD sum rules approach. Our results show that the nonfactorizable corrections from the soft-gluon exchanges in the decay B\ensuremath→\ensuremathηcK are of (15\ensuremath-30)% and should be taken into account. As for the decay B\ensuremath→\ensuremathχc0K, the factorizable contributions are zero and the nonfactorizable contributions from the soft hadronic matrix elements are too small to accommodate the experimental data.
