On two occasions, the kowtow was performed by Chinese envoys to a foreign ruler – specifically the Russian Tsar. T'o-Shih, Qing emissary to Russia whose mission to Moscow took place in 1731, kowtowed before Tsarina Anna, as per instructions by the Yongzheng Emperor, as did Desin, who led another mission the next year to the new Russian capital at St. Petersburg. Hsu notes that the Kangxi Emperor, Yongzheng's predecessor, explicitly ordered that Russia be given a special status in Qing foreign relations by not being included among tributary states, i.e. recognition as an implicit equal of China.
