[Title] The Taft - Katsura Agreement
... COUNT KATSURA and Secretary Taft had a long and confidential conversation on the morning of July 27....
First, in speaking of some pro-Russians in America who would have the public believe that the victory of Japan would be a certain prelude to her aggression in the direction of the Philippine Islands, Secretary Taft observed that Japan’s only interest in the Philippines would be, in his opinion, to have these islands governed by a strong and friendly nation like the United States,…Count Katsura confirmed in the strongest terms the correctness of his views on the point and positively stated that Japan does not harbor any aggressive designs whatever on the Philippines....
