The ability of Qing China to project power into Central Asia came about because of two changes, one social and one technological. The social change was that under the Qing dynasty, from 1642, the Chinese military forces were organized around cavalry which was more suited for power projection than prior Chinese infantry. The technological change was advances in artillery which negated the military advantage that the people of the steppe had with their cavalry.
