Four reasons why China is not ready to lead the world though
US leadership is dying:

1) Trump will continue doing his best to contain China.
2) China has too few bases around the world, which significantly limits its global influence. Meanwhile, building more bases during peacetime is too sensitive, and can't be accomplished in a short time.
3) Like US, China's economy is also problematic. CNY is also not ready to become a global reserve currency. Gigantic paradigm reforms are needed in China's economy.
4) China's current 2035 vision doesn't tell too much about its global interference. Which means its leaders are still not ready to do too much abroad.
