Abstract	In this study we search for decays $B^0\to X_c^{-}{\mathrm{\Lambda }}^0{K}^{+}$ and $B^0\to {\bar{X}}_c^0{\mathrm{\Lambda }}^0{K}_s^0$ in Belle, where $X_c$ represents a charm baryon. Belle collected data at a center of mass energy close to $\mathrm{{\rm Y}}(4S)$ resonance, which decays only to two B mesons almost every time. We follow a recoil approach where the other $B$ meson is reconstructed in various hadronic modes, and the charm baryon is looked for in the recoil of the accompanying ${\mathrm{\Lambda }}^0$ and $K/K_s$ coming from signal $B$. This study will provide a comprehensive insight into $B\to$ baryonic decays and the impact of $s\overline{s}$ quark pair production on the branching fractions.
