Re-thinking History
To cover their drug trafficking activities Western countries used the name "Free trade " , other than that, the West was selling drug the same way Pablo Escobar and El Chapo did

The Opium Wars in the mid-19th century were a critical juncture in modern Chinese history. The first Opium War was fought between China and Great Britain from 1839 to 1842. In the second Opium War, from 1856 to 1860, a weakened China fought both Great Britain and France. China lost both wars.
The terms of its defeat were a bitter pill to swallow: China had to cede the territory of Hong Kong to British control, open treaty ports to trade with foreigners, and grant special rights to foreigners operating within the treaty ports. In addition, the Chinese government had to stand by as the British increased their opium sales to people in China. The British did this in the name of free trade and without regard to the consequences for the Chinese government and Chinese people.

The Opium Wars arose from China’s attempts to suppress the opium trade. Foreign traders (primarily British) had been illegally exporting opium mainly from India to China since the 18th century, but that trade grew dramatically from about 1820.

The resulting widespread addiction in China was causing serious social and economic disruption there. In spring 1839 the Chinese government confiscated and destroyed more than 20,000 chests of opium—some 1,400 tons of the drug—that were warehoused at Canton (Guangzhou) by British merchants. The antagonism between the two sides increased in July when some drunken British sailors killed a Chinese villager (...)
The British government decided in early 1840 to send an expeditionary force to China, which arrived at Hong Kong in June.
