The main purpose of this paper is to prove the uniqueness of Einstein Kähler metrics on an arbitrary compact complex manifold X with positive first Chern class \(c_ 1(X)_ R>0\) up to G-action. Such uniqueness was known only for: i) Kähler C-spaces [see Y. Matsushima, Nagoya Math. J. 46, 161-173 (1972; Zbl 0249.53050)] and ii) some non- homogeneous Einstein manifolds - recently discovered by Y. Sakane [see Examples of compact Einstein Kähler manifolds with positive Ricci tensor, Osaka J. Math. (to appear)].
