He has the initiative to return the Amur, ceded to China in 1689. He assisted to Nevelskoy G.I. in his investigations. Despite the opposition in St. Petersburg, Muravyov managed to achieve the fact that the mouth of Amur occupation was accepted by the Tsar.
In 1854, Emperor Nicholas I gave to Muravyov the right to delimitate the eastern outskirts with the Chinese government and also he was allowed to make a combination of troops along the Amur river.
