What kind of foreign policy was implemented in the early Qing Dynasty? What is the result of this policy?

The Qing Dynasty implemented a strict policy of forbidding the sea, strictly restricted foreign trade and closed its doors to the outside world. Only 13 banks in Guangzhou are open to the public.

This influence has both positive and negative aspects.

Positive: resisted the colonial expansion of the West at that time and protected its own interests. At the same time, the development of agricultural economy created the last prosperous period of feudal economy in China's ancient history-the prosperous period of Kanggan.

Negative: China has been isolated from the world for a long time, and has gradually fallen behind the West in system and technology, so that the Opium War, the Second Opium War, the Sino-Japanese War of 1894-1895 and Eight-Nation Alliance's invasion of China were all disastrous. Become a semi-colonial and semi-feudal society.
