Actually a defensible statement.
Certainly it has pulled more people (in raw numbers) above the absolute poverty level than any other economy. Its sustained economic growth is also quite unusual.
My browser choked on the link, but I suspect the author never bothers to explain why China's economic growth is NOT "an accomplishment unparalleled in human history."
I hate it when writers do that.
Try post WWII South Korea or Germany.
I would kind of give the invention of fire priority over the Chinese economy.
