Another excerpt from Stiglitz :
"Although we in the West tend to forget, 190 years ago one-third of the world’s gross domestic product was in China. But then, rather suddenly, colonial exploitation and unfair trade agreements, combined with a technological revolution in Europe and America, left the developing countries far behind, to the point where, by 1950, China’s economy constituted less than 5 percent of the world’s G.D.P. In the mid–19th century the United Kingdom and France actually waged a war to open China to global trade. This was the Second Opium War, so named because the West had little of value to sell to China other than drugs, which it had been dumping into Chinese markets, with the collateral effect of causing widespread addiction. It was an early attempt by the West to correct a balance-of-payments problem."
