On April 10, 1840, the House of Commons of the British Parliament passed the case on military expenditures against China and the resolution that "British businessmen must achieve satisfactory compensation for their losses in China." A month later, the upper house of parliament unanimously passed the bill. The 19th century was the heyday of the British Empire. After successively occupying parts of Singapore and Myanmar, and invading Afghanistan and Iran, Britain stepped up its aggression against China in order to turn China into its commodity market and raw material production area. In September 1839, after receiving a report from the Commerce Supervision Law in China on smoking bans in China, the British government decided to send a navy to "expedition" to China. The London capitalists established a committee with the participation of Charton, a big opium trader who fled from China, and others to instigate the war of aggression against China. Chambers of commerce in Manchester, London, Leeds, Liverpool, Brest and other places have written to Foreign Secretary Palmerston, demanding that force be used against China to protect their trade interests. On January 16, 1840, Queen Victoria delivered a speech in Parliament, claiming that smoking bans in China had caused losses to the interests of British businessmen and affected the "dignity" of the British king. On February 20, Yilv and Yilv were appointed as the plenipotentiary representatives and deputy plenipotentiaries for negotiations with China, and specific instructions were given on the steps of aggression against China. On March 19, the British government announced in the House of Commons its decision and intention to "expedition" to China. From April 7 to 9, the Parliament held a debate on the war against China. Finally, the British government decided to launch a war against China in order to meet the demands of the opium interest group, which risked plunder and sought wealth, and the industrial bourgeoisie-the textile interest group, which was eager to open up the China market.
