Lifan Yuan
At the start of the dynasty, the Chinese empire continued to be the hegemonic power in East Asia. Although there was no formal ministry of foreign relations, the Lifan Yuan was responsible for relations with the Mongol and Tibetans in Central Asia, while the tributary system, a loose set of institutions and customs taken over from the Ming, in theory governed relations with East and Southeast Asian countries. The Treaty of Nerchinsk (1689) stabilized relations with Czarist Russia.
