Shameful Westerners from Spain Britain France Italy Germany Portugal Netherlands & USA etc  went round the world in 17-19th centuries and used underhand tactics to swindle cheat and rob the locals all their treasures to become rich and then used the same loots to fund industrialisation. 
China was the victim in the hand of British (HK & Canton), Portuguese (Macau), French (Shanghai), German ( Qingdao) Spaniard (Taiwan), Japanese (NE China)
