In the meantime Russia steadily increased her hold upon Manchuria, and large bodies of troops continued to be poured into the country. Her position had now become so strong in the counsels of the Chinese Court that in July, 1898, she openly opposed the concession, which British capitalists were seeking, of an extension of the Northern Railways of China to the Treaty Port of Niuchwang, which lies to the north of Port Arthur, at the extremity of the Gulf. The importance of this extension to British and American commerce was immense. Niuchwang is the main outlet of the trade of Manchuria, and was at that time a busy thriving town of about 60,000 inhabitants. Its value from the commercial point of view may be estimated from the fact that its total trade rose from £1,850,000 in 1881 to £7,253,650 in 1899, the year before it fell absolutely into Russian hands. Russia's attempt to deprive her commercial rivals of practical access by land to this valuable port were, however, on this occasion only partially successful; the construction of the Shan-hai-Kwan-Niuchwang Railway was finally permitted; but the agreement was greatly modified to suit Russian views. [Sidenote: Pavloff in Korea] Concurrently with these events, significant developments had been taking place in Korea, which brought Japan once more upon the stage. For some time after the Japanese had been driven from Port Arthur, Russia left Korea alone. She even entered into formal engagements with Japan, recognizing that Power's peculiar commercial rights and interests in Korea. But now M. Pavloff arrived upon the scene at Seoul. In March, 1900, he gave the Japanese the first taste of his quality by endeavoring to obtain a lease of the important strategic port of Masampo, situated in the southeast of Korea, facing the Japanese coast and dominating the straits between. At the same time he stipulated that the Korean Government should not alienate to any other Power the island of Kojedo, which lies just opposite to Masampo. Japan successfully resisted this bold stroke of policy; and matters were in this position when the Boxer rising gave Russia a supreme opportunity. Her troops in Manchuria were attacked by the rebels, and she at once hurried in reinforcements and seized the whole country. Resistance to her arms was put down with relentless vigor--with a vigor, indeed, far transcending the necessities of the case, and the Blagovestchensk massacres, in which thousands of unarmed Chinamen were offered up as a sacrifice to the offended majesty of Russia, will long be a stain upon the escutcheon of the Imperial Prophet of Peace. In the drastic process of absorption which was now adopted, the treaty port of Niuchwang was naturally included, and the interests of other Powers there became of very small account indeed.
