Question

Source: Modern historical analysis of early modern empires.

'In the early modern era, both the Romanov dynasty in Russia and the Qing dynasty in China undertook massive campaigns of territorial expansion into Central and Northern Asia. For Russia, the conquest of Siberia was driven by the lucrative fur trade, where the state secured its authority by imposing the *yasak*—a tribute paid in pelts—upon indigenous communities. The tsars largely left the internal structure of Siberian clans intact, relying on native chiefs to collect the tribute. For the Qing, the incorporation of Mongolia, Xinjiang, and Tibet led to the creation of the *Lifan Yuan* (Court of Colonial Affairs). Rather than imposing Han Chinese cultural norms or direct bureaucratic rule, the Qing administered these regions through local elites, such as Mongol princes and Muslim begs, keeping the frontier territories separate from the traditional Chinese provinces.'

Based on the passage and your knowledge of world history, which of the following best describes the primary strategy used by both the Qing and Russian empires to consolidate their control over diverse frontier populations?
