Treaty of Nerchinsk
Zeleny Klyn became part of the Russian Empire much later than Siberia and other parts of the Far East. The first attempts at colonizing the area date back to the mid-17th century when Yerofey Khabarov founded the fort of Albazin on the Amur River. From that time, constant skirmishes took place with the Manchu people of China. In 1689 China and Russia signed the Treaty of Nerchinsk, which granted Russia limited territory.
