We analyze B --> K H-c (where H-c = eta(c) J/psi, chi(cJ(J=0.1))) decays estimating nonfactorizable contributions from the light-cone sum rules (LCSR). Nonfactorizable contributions are sizable for B --> K J/psi and particularly for B --> K chi(c1) decay. For the B decays into a (pseudo)scalar charmonia we find small nonfactorizable contributions which cannot accommodate relatively large branching ratios obtained by measurements. This specially concerns the puzzling B --> K chi(c0) decay. (C) 2004 Elsevier B.V. All rights reserved.
