According to the provisions of the treaty of nanking, the first British consul in Shanghai, Buffor, came to Shanghai to set up a British consulate, and coerced the then Shanghai Daotai Gongmuhuo to pass the Shanghai Lease Charter, allocating about 550,000 square meters of land north of Pidgin and south of Li Jiazhuang to the British for living, which was also the first concession occupied by foreign powers in Chinese mainland.
Treaty of nanking, also known as Jiangning Treaty, is the first unequal treaty signed by China with foreign countries in modern history. It involves land transfer, compensation, five-port trade and tax negotiation.
1842 (twenty-two years of Qing Daoguang), the Qing Dynasty was defeated in the first opium war with Britain. The Qing government was forced to sign the Sino-British treaty of nanking with Britain at the British flagship Cornwally (Gao Yi Wally) on the Xiaguan River in Nanjing (called Jiangning in Japan). Treaty of nanking is the first unequal treaty imposed on the people of China by modern western capitalist countries.
Britain forced China to accept its aggression demand by military aggression, which destroyed China's independent status as a sovereign country. The British occupation of Hong Kong Island destroyed China's territorial integrity and lost its independent status. Five-port trade became the center of colonial plunder and unequal exchange of China by western capitalism.
The huge compensation increased the financial burden of the Qing government, and at the same time it was passed on to the working people, making their lives more difficult. After the signing of treaty of nanking, western powers took advantage of the fire to rob and forced the Qing government to sign a series of unequal treaties. Since then, China has gradually become a semi-colonial and semi-feudal society.
