>>13303244eh, not really. their population is over 4 times our size and our GDPs are still neck and neck. their population is projected to decline, while ours is projected to grow. their GDP per capita and HDI are both terrible compared to western countries. plus more and more things are becoming automated and AI will become a thing, so I doubt china will do anything other than become the biggest trading partner in the eastern hemisphere.
>As of 2021, the United States and China would occupy the first two places in both methods' gdp ranking. The US and China's margin is coming down in nominal ranking as China's gdp growth rate of 2021 (8.44%) is higher than the US's 6.39%. On a nominal basis, the US is ahead of China by $6 trillion in 2021 compared to $6.2 trillion in 2020. On a ppp basis, China has overtaken the US in 2017 and ahead by Int. $4 trillion, and the gap is increasing. China will remain the world's largest economy on a ppp basis over the next few decades as 2nd ranked US is growing slow and 3rd ranked India is way behind.
