The Chinese wanted opium!

The British needed Chinese goods, primarily tea, but the Chinese didn't need anything from the British. That would leave a trade deficit on the British side, so they got the Chinese nation addicted to opium (unprocessed heroin) which they produced in India. When the Chinese emperor tried to ban opium, the Chinese people rebelled against him, backed by the British, which led to Opium wars.
