We discuss angular convergence of Riemannian Brownian motion on a Cartan-Hadamard manifold and show that the Dirichlet problem at infinity for such a manifold is uniquely solvable under the curvature conditions -Ce(2-η)ar(x) ≤ KM(X) ≤ -a2 (η > 0) and -Cr(x) ≥ KM(x) ≤ -α(α- 1)/r(x)2 (α > β+ 2 > 2), respectively.
