Abstract: We study some geometric properties of a compact Kähler manifold $ (M^n, g)$ under a certain condition on the bisectional curvature. As an application, we give a new proof for an earlier result which asserts that any boundary class of the Kähler cone of $ M^n$ can be represented by a $ C^{\infty}$ closed (1,1) form that is parallel and everywhere nonnegative.
