Roy E. Appleman, the author of US Army official history South to Naktong, North to Yalu, writes that both sides could claim victory: the PVA 9th Army ultimately held the battlefield, while X Corps held off the Chinese 9th Army in a series of battles that enabled it to withdraw most of its forces as an effective tactical unit.[1]:355–6 Allan R. Millett qualifies a Chinese "geographic victory" that ejected X Corps from North Korea with the fact that the Chinese failed to achieve the objective of destroying the 1st Marine Division, adding that the campaign gave the UN confidence that it could withstand the superior numbers of the Chinese forces.[49] The official Chinese history, published by PLA Academy of Military Science, states that despite the heavy casualties, the PVA 9th Army had earned its victory by successfully protecting the eastern flank of Chinese forces in Korea, while inflicting over 10,000 casualties to the UN forces.[50]

"[the Russian reinforcements were coming down to the fort on the river] Thereupon he [Marquis Lin] ordered all our marines to take off their cloths and jump into the water. Each wore a rattan shield on his head and held a huge sword in his hand. Thus they swam forward. The Russians were so frightened that they all shouted: 'Behold, the big-capped Tartars!' Since our marines were in the water, they could not use their firearms. Our sailors wore rattan shields to protect their heads so that enemy bullets and arrows could not pierce them. Our marines used long swords to cut the enemy's ankles. The Russians fell into the river, most of them either killed or wounded. The rest fled and escaped. Lin Hsing-chu had not lost a single marine when he returned to take part in besieging the city." written by Yang Hai-Chai who was related to Marquis Lin, a participant in the war
Most of the Russians withdrew to Nerchinsk, but a few joined the Qing, becoming the Albazin Cossacks at Peking. The Chinese withdrew from the area, but the Russians, hearing of this, returned with 800 men under Aleksei Tolbuzin and reoccupied the fort. (their original purpose was merely to harvest the local grain, a rare commodity in this part of Siberia.) From June 1686, the fort was again besieged. Either (the siege was raised in December when it was learned that the two empires were engaged in peace negotiations) or (the fort was captured after an 18 month siege and Tolbuzin killed). At that time less than 100 defenders were left alive.
In 1689, by the Treaty of Nerchinsk, the Russians abandoned the whole Amur country including Albazin. The frontier was established as the Argun River and the Stanovoy Range. In 1727 the Treaty of Kyakhta confirmed and clarified this border and regulated Russo-Chinese trade.
