The Treaty of Tianjin (Tientsin) in 1858 changed the situation of the Beijing mission radically. The treaty admitted to China representatives of foreign governments and rights of residence in China to Christian missionaries. In the new period diplomatic and religious activities of the Beijing Mission were separated. Translations of the Scriptures began to appear. The Mission head, Archimandrite Gury Karpov, participated actively in the negotiations of the Beijing Treaty of 1860 under which Russia gained lands along the Amur River. Having studied Chinese for many years he was active also in translating the New Testament into Chinese, as well as collecting earlier translations of Orthodox books for re-translation into the Chinese spoken language. He expanded preaching and lecturing in church, reaching areas beyond Beijing.
While the literary and translation efforts continued through most of the later part of the nineteenth century, the missionary work in the later part of the century lagged due to inadequate funding for preaching outside of Beijing as well as the arrival of new missionaries whose Chinese language skills were inadequate. The era of an all-Russian [[clergy]] ended when a Chinese priest, Fr. Mitrofan Ji, was [[ordination|ordained]] in Japan by [[Nicholas of Japan|Abp. Nicholas]] of Tokyo. Fr. Mitrofan died a [[martyr]] in the [[June 11]], 1900 Boxer uprising in China. The about 500 baptisms that had been performed by the Mission and the establishment of two new churches, one each in Hankou and Kalgan (Zhangjiakou) had not contributed significantly to the Mission’s missionary efforts.
With the arrival of Archimandrite [[Innocent (Figurosky) of Beijing|Innocent]] in March 1897 the situation change abruptly. Fr. Innocent immediately undertook reforms in the Mission: he established a monastery, instituted daily services in Chinese, established support for Albasins with business abilities, organized parish activities, dispatched preachers to the hither lands outside Beijing to spread the [[Gospel]], and established charity efforts among the local poor. While Fr. Innocent’s arrival began a period of active missionary efforts, the beginning of the twentieth century also brought serious troubles for the Russian Orthodox Mission, as it did for other Christian missions. The Boxer (Yihetuan Movement) revolt in 1900 resulted in the destruction of the buildings in Beijing, Dongdingan, and Kalgan (Zhangjiakou). The riots caused the death of more than 200 Orthodox faithful. The losses also included the extensive library in the Beijing compound begun by Archimandrite Peter during the tenth mission. The Mission survived, and by 1902 there were 32 churches in China with nearly 6,000 members
