The second unequal treaty in China's modern history is

Treaty of nanking (1842 (22nd year of Daoguang), August 29th, Nanjing, England)?

Treaty of Humen (1843 (23 years of Daoguang) 10/0/8 October, with Britain, Humen)

Wang Xia Treaty (1844 (24th year of Daoguang), signed with the United States and Wang Xia on July 3rd).

The Treaty of Nebuchadnezzar Chu is not an unequal treaty;

Historically, China and Russia were politically independent, economically independent and militarily weak. The Sino-Russian battle in jaxa was a complete victory for China. When China and Russia signed the treaty, they were not oppressed by each other's military. The two sides signed the Treaty of Nebuchadnezzar Chu voluntarily, so the Treaty of Nebuchadnezzar Chu is an equal treaty.

The Treaty of Nebuchadnezzar is not a cession treaty, but a treaty dividing Gorkha tribal areas between China and Russia, which is the first step of dividing outer Mongolia between Qing and Russia. After the signing of the treaty, the Gurkha Mongols had no further retreat, so they had to move south and gradually moved to Inner Mongolia Autonomous Region of China.
