Legal analysis: The signing of treaty of shimonoseki has brought great harm to China; In short (1), a large area of China became a Japanese colony, which facilitated Japan's further aggression against China. (2) The huge reparations increased the burden on the people of China and strengthened the aggressive strength of Japanese imperialism. At the same time, because the Qing government was unable to pay huge reparations, it provided opportunities for other imperialists to control China's economy with loans. (3) Opening commercial ports located in the richest Yangtze River valley has facilitated the economic plunder of these areas by imperialist countries. (4) Allowing Japanese to set up factories in trading ports promoted the export of imperialist capital to China. To sum up, treaty of shimonoseki has greatly deepened the colonial and semi-colonial degree of China.
