Abagaita

Abagaita lies in the grasslands near the upper Argun, where the river turns north from the Hulunbuir country. In 1727 Qing and Russian officials surveyed the frontier east of Kyakhta, setting markers across the steppe and exchanging a boundary agreement at Abagaitu. The river itself had already been named as a boundary in the Treaty of Nerchinsk. Its broad valley links the open pastures around Lake Hulun with the wooded country downstream.
