Recent studies of kaonic atoms, few-body kaonic quasibound states and kaonic nuclei based on s-wave ${\bar K}N$ chiral interaction models that are consistent with the SIDDHARTA $K^-$ hydrogen data are reviewed, focusing on the $K^-pp$
dibaryon. Remarks are made on low-lying dibaryons other than $\Lambda(1405)N$, particularly those involving p-wave interactions of pions with octet baryons.
