Hyperon--nucleon as well as kaon--nucleon interaction models, which have recently been developed in the meson exchange framework by the Juelich group, are reviewed. In case of the hyperon--nucleon interactions, polarization data are urgently needed to discriminate between various models. From such a consistent study of the KN and {bar K}N systems, it can be concluded that (1) the {Lambda}(1405) is a quasibound {bar K}N state, (2) the assumption of the short-ranged repulsion in the KN system being completely due to vector-meson exchange is incompatible with empirical {bar K}N data. A possible source for additional repulsion is discussed in connection with the chiral bag model.
