From time immemorial China's policy towards the petty states on her frontiers had been to utilize them as buffers for softening the shock of foreign contact, while contriving, at the same time, that her relations with them should involve no inconvenient responsibilities for herself. The aggressive impulses of the outside world were to be checked by an unproclaimed understanding that the territories of these states partook of the inviolability of China, while the states, on their side, must never expect their suzerain to bear the consequences of their acts. This arrangement, depending largely on sentiment and prestige, retained its validity in the atmosphere of Oriental seclusion, but quickly failed to endure the test of modern Occidental practicality. Tongking, Annam, Siam and Burma were withdrawn, one by one, from the fiction of dependence on China and independence towards all other countries. But with regard to Korea, China proved more tenacious. The possession of the peninsula by a foreign power would have threatened the maritime route to the Chinese capital and given easy access to Manchuria, the cradle of the dynasty which ruled China. Therefore Peking statesmen endeavoured to preserve the old-time relations with the little kingdom. But they could never persuade themselves to modify the indirect methods sanctioned by tradition. Instead of boldly declaring Korea a dependency of China, they sought to keep up the romance of ultimate dependency and intermediate sovereignty. Thus in 1876 Korea was suffered to conclude with Japan a treaty of which the first article declared her "an independent state enjoying the same rights as Japan," and subsequently to make with the United States (1882), Great Britain (1883) and other powers, treaties in which her independence was constructively admitted. China, however, did not intend that Korea should exercise the independence thus conventionally recognized. A Chinese resident was placed in Seoul, and a system of steady though covert interference in Korea's affairs was inaugurated. The chief sufferer from these anomalous conditions was Japan. In all her dealings with Korea, in all complications that arose out of her comparatively large trade with the peninsula, in all questions connected with her numerous settlers there, she found herself negotiating with a dependency of China, and with officials who took their orders from the Chinese representative. China had long entertained a rooted apprehension of Japanese aggression in Korea--an apprehension not unwarranted by history--and that distrust tinged all the influence exerted by her agents there. On many occasions Japan was made sensible of the discrimination thus exercised against her. Little by little the consciousness roused her indignation, and although no single instance constituted a ground for strong international protest, the Japanese people gradually acquired a sense of being perpetually baffled, thwarted
