Your Invention of... series looks at how history has made nations what they are today. Why did you choose to focus on China in these latest episodes?
After 30 years of US domination, the last 15 years have seen the so-called multipolar world emerge. But within that multipolarity you have two great powers, with China now America’s main rival. There should be a third great power, Europe, but it’s not politically coherent enough to act in the way that both the US and China do.
