Урянхайский край
Indeed, there is no evidence that Tannu Uriankhai was ever visited by a senior Qing official (except perhaps in 1726). Chinese merchants were forbidden to cross the pickets, a law not lifted until the turn of the 20th century. Instead, a few days were set aside for trade at Uliastai when Uriankhai nobles delivered their annual fur tribute to the military governor and received their salaries and other imperial gifts (primarily bolts of satin and cotton cloth) from the emperor. Thus, Tannu Uriankhai enjoyed a degree of political and cultural autonomy unequalled on the Chinese frontier.
