What were the results of the treaty of Nanking?

The Treaty of Nanking, signed in 1842, marked the end of the First Opium War between Britain and China. As a result, China ceded Hong Kong to Britain, opened five ports to British trade, and granted extraterritorial rights to British citizens. Additionally, China agreed to pay a large indemnity, significantly weakening its sovereignty and paving the way for further foreign intervention in Chinese affairs.
