In the light of a few authentic documents and many subsequent events, the outline of this plan can be traced with tolerable accuracy. In the region through which the projected railways were to run there was a large marauding population, and consequently the labourers and the works would have to be protected; and as Chinese troops can never be thoroughly relied on, the protecting force must be Russian. Under this rather transparent disguise a small army of occupation could be gradually introduced, and in establishing a modus vivendi between it and the Chinese civil and military authorities a predominant influence in the local administration could be established. At the same time, by energetic diplomatic action at Peking, which would be brought within striking-distance by the railways, all rival foreign influences might be excluded from the occupied provinces, and the rest might be left to the action of "spontaneous infiltration." Thus, while professing to uphold the principle of the territorial integrity of the Celestial Empire, the Cabinet of St. Petersburg might practically annex the whole of Manchuria and transform Port Arthur into a great naval port and arsenal, a far more effectual "Dominator of the East" than Vladivostok, which was intended, as its name implies, to fulfil that function. From Manchuria the political influence and the spontaneous infiltration would naturally extend to Korea, and on the deeply indented coast of the Hermit Kingdom new ports and arsenals, far more spacious and strategically more important than Port Arthur, might be constructed.
The grandiose scheme was carefully laid, and for a time it was favoured by circumstances. In 1900 the Boxer troubles justified Russia in sending a large force into Manchuria, and enabled her subsequently to play the part of China's protector against the inordinate demands of the Western Powers for compensation and guarantees. For a moment it seemed as if the slow process of gradual infiltration might be replaced by a more expeditious mode of annexation. As the dexterous diplomacy of Ignatief in 1858 had induced the Son of Heaven to cede to Russia the rich Primorsk provinces between the Amur and the sea, as compensation for Russian protection against the English and French, who had burnt his Summer Palace, so his successor might now perhaps be induced to cede Manchuria to the Tsar for similar reasons.
No such cession actually took place, but the Russian diplomatists in Peking could use the gratitude argument in support of their demands for an extension of the rights and privileges of the "temporary" occupation; and when China sought to resist the pressure by leaning on the rival Powers she found them to be little better than broken reeds. France could not openly oppose her ally, and Germany had reasons of her own for conciliating the Tsar, whilst England and the United States, though avowedly opposing the scheme as dangerous to their commercial interests, were not prepared to go to war in defence of their policy. It seemed, therefore, that by patience, tenacity and diplomatic dexterity Russia might ultimately attain her ends; but a surprise was in store for her. There was one Power which recognised that her own vital interests were at stake, and which was ready to undertake a life-and-death struggle in defence of them.
Though still smarting under the humiliation of her expulsion from the Liaotung Peninsula in 1895, and watching with the keenest interest every move in the political game, Japan had remained for some time in the background, and had confined her efforts to resisting Russian influence in Korea and supporting diplomatically the Powers who were upholding the policy of the open door. Now, when it had become evident that the Western Powers would not prevent the realisation of the Russian scheme, she determined to intervene energetically, and to stake her national existence on the result. Ever since 1895 she had been making military and naval preparations for the day of the revanche, and now that day was at hand. Against the danger of a coalition such as had checkmated her on the previous occasion she was protected by the alliance which she had concluded with England in 1902, and she felt confident that with Russia alone she was quite capable of dealing single-handed.
Her position is briefly and graphically described in a despatch, telegraphed at that time (28th July, 1903) by the Japanese Government to its representative at St. Petersburg, instructing him to open negotiations:
"The recent conduct of Russia in making new demands at Peking and tightening her hold upon Manchuria has led the Imperial Government to believe that she must have abandoned her intention of retiring from that province. At the same time, her increased activity upon the Korean frontier is such as to raise doubts as to the limits of her ambition. The unconditional and permanent occupation of Manchuria by Russia would create a state of things prejudicial to the security and interests of Japan. The principle of equal opportunity (the open door) would thereby be annulled, and the territorial integrity of China impaired. There is, however, a still more serious consideration for the Japanese Government. If Russia were established on the flank of Korea she would constantly menace the separate existence of that Empire, or at least exercise in it a predominant influence; and as Japan considers Korea an important outpost in her line of defence, she regards its independence as absolutely essential to her own repose and safety.
Moreover, the political as well as commercial and industrial interests and influence which Japan possesses in Korea are paramount over those of other Powers; she cannot, having regard to her own security, consent to surrender them to, or share them with, another Power."
