Last week. the underling causes leading to the opening of China were examined. This week, I would like to examine and discuss the events and the immediate causes which || 1.0 the outbreak of the First Anglo-Chinese War. In addition, I would analyse how China was opened to foreign trade after the war and the overall effect which the war Mac on her.

The immediate cause which led to the outbreak of the First Anglo-Chinese Har.

A.

1.

The issue of opium

Why did Britain export opium to China and what was its consequence? Throughout the 18th century, Sino- British trade developed not in Britain's favor. Trade deficit grew year after year because British imported a large amount of Chinese products, such as tea and silk, whereas since Cirina remained agrarian country and since she was self-sufficient economically, she did not need much foreign goods. As result, British merchants spent a huge amount of silver in buying Chinese products. To change the trading conditions. British Inerchants exported opium to China.

When considered from moralistic point. of VIEW.. the import of opium had to be barred since opium had an adverse effect on the health of Chinese people.

the British government.

To sum up, the following events and causes could be regarded as the cacses for the First. Anlgo-Chinese War. They are:

1. the issue of opium

Comments and the significance of the Treaty of Nanjing on China.

1. The treaty was superimposed by Britain and China was not treated fairly.

2. Economically, Chine had to pay huge!

indemnity since she was forced to pay 21 million taels of silver as indemnity.
