Which events have been most important in the development of china, mongolia, and taiwan? (1 or 2 paragraphs)

Here is what I suggest: Google economic development then add the country name. I did that and several good sites popped up. 
For Mongolia, there is a current event (Global Climate Change) that is affecting Mongolia in  that it's huge coal resources are going broke, putting many out of work as the big customer, China, is cutting way back on coal for power generation because of air pollution. You willhave difficulty finding this in modern literature, because of the climate doubters...however, you can see the effects on Mongolia coal mining the past three years..
