To answer your question - main lobbyst behind first Opium War was Scottish opium trader James Matheson [2]. The fortune he had made on selling opium to China had been invested in Rio Tinto[3] - mining company that survived till today.

Is there a name for this fallacy? It seems to come up a lot. I.e., when someone takes an action that has enormous and predictable negative effects for someone else and a comparatively tiny positive effect for themselves, they then argue along the lines that "I was motivated by my gain, not by your loss (even though I knew it would result from my action), so you have no right to complain!"
In this case, it can be both a "deliberate conspiracy" and a "pragmatic response". They deliberately conspired to hurt the Chinese for profit, judging their suffering to be a less important consideration than their own profits.
