We propose a new easy method to control a sign of the subnatural resonances of electromagnetically-induced transparency and absorption in the Hanle configuration under counterpropagating light waves. The analytical results for a three-level atomic Λ-scheme are corroborated by numerical calculations for various atomic transitions. The results can be applied in nonlinear optics, optical communications and magnetometry.
