Let diam min (G) denote the minimum diameter of a strong orientation of G and let G H denote the strong product of graphs G and H. In this paper we prove that diam min (P m P n) = diam(P m P n) for m, n ≥ 5, m = n, and diam min (P m P n) = diam(P m P n) + 1 for m, n ≥ 5, m = n. We also prove that diam min (G H) ≤ max {diam min (G), diam min (H)} for any connected bridgeless graphs G and H.
