Final answer:
Canton (Guangzhou) would have mostly depended on the trade between China and the West due to its role as a major port for foreign trade.
Step-by-step explanation:
The city that would have mostly depended on the trade between China and the West is Canton (also known as Guangzhou), located in southern China.
The Europeans wanted access to China for their cotton fabrics and silverware, as well as to sell opium. Opium was grown in India by the British East India Company and exported to China, leading to two Opium Wars.
As a result, China was eventually forced to open all its ports to foreign trade, including Canton, making it a major city for trade between China and the West.
