BTW, a little factoid about Communism. Something that will irk Christian evangelists. Marx didn't even invent Communism. The early Christians did and they put it into practice.
Basically, early Christians lived in communes, which is the source of the word, Communism. In those communes, they gave up their worldly material possessions---remember this is what Christ said---so they could share these possessions with everyone in the communes equally.
As for the opium wars, its remarkable to think that the USA's dependence on Chinese goods and subsequent trade imbalance and wealth outflow has its historical precedents. It happened over two thousand years before with the Roman Empire with the Silk route, as the Romans lavished and wasted their wealth on their addiction to silk, which they only know is made from a mythical far off country known only as Serenica.
It also happened with the British Empire who became addicted to the Chinese porcelains, silk, and most of all, tea. The British however, ran out of things to pay for their addiction, considering that the Chinese would only accept silver, not even gold, as payment for these things. Pretty much there was nothing the British could sell to the Chinese, since the Chinese actually felt that the British stuff were barbarian, lacked the art and skill of the Chinese products. This is one of the things that fueled the Opium trade, when Opium is used instead to sell to the Chinese, and the money obtained from selling Opium is used to buy silk, porcelains (which soon entered into the English language as "china"), and of course, tea. Thus this began a cycle of draining economic wealth from China, from a country with the highest GDP in the world, to its impoverished state at the end of the Qing Dynasty.
