Is Thierry Aubin’s theorem true on Hermitian manifolds? A classical theorem of Thierry Aubin states that:

Theorem (Aubin, T. 1979): If the Ricci curvature of a compact Riemannian manifold is
  non-negative and positive at a point, then the manifold carries a metric of positive
  Ricci curvature.

In the study of structures on manifolds (such as Hermitian, Kaehlerian, symplectic,...) is the above theorem true? e.g.

Question: Does "the Ricci curvature of a compact Hermitian manifold is
  non-negative and positive at a point", imply "the manifold carries a Hermitian metric of positive
  Ricci curvature"?

Your suggestions will be appreciated.
 A: EDIT:
The content below and at the comments rely on Kahler manifolds, and this does not intend to be a complete or even satisfactory answer:
The case when the first Chern class is positive is rather delicate. It was disproved by Yau that even provided the manifold possess positive first Chern class, then there is no ensure for example that the manifold admits a positive Kähler Einstein metric. Also, even when the Kähler–Einstein metric exists, it need not be unique. 
Further, a necessary condition for the existence of a Kähler–Einstein metric is that the Lie algebra of holomorphic vector fields is reductive. It was conjectured by Yau that provided the first Chern class is positive, a Kähler manifold has a Kähler–Einstein metric if and only if it is stable in the sense of geometric invariant theory.

A necessary condition (assuming Kähler) to this rely on the fact the first Chern class of manifold is positive. Since the Ricci curvature of an hermitian metric is connected with its Ricci form, that determines the first Chern class. 
On the otherside, provided $c_1(M) > 0$ and the manifold is compact and Kähler, then by the Calabi-Yau theorem your requirement is true.
