but all exertions were fruitless. The Chinese government simply wanted nothing to do with foreigners or their products. 2In 1759 Emperor Qianlong had restricted European commercial presence to Guangzhou, a port in the southeastern part of China. There the trade was very much supervised by Chinese under the cohong system, with specially licensed Chinese firms operating under government set prices. Trade with Europeans was also restricted by the fact that Europeans had very little that the Chinese wanted to buy, even though the reverse was far from true. So the British East India Company, using Turkish and Persian expertise grew opium in India and shipped it to China. As a result, trade boomed, especially once the Chinese developed addictions to the drug. The weak Qing government failed to act, even after some Chinese officials began to support the trade by accepting bribes. In 1838, with about 40,000 chests of opium coming into Guangzhou that year, the government finally tried to stop it.
