No chance China will over take the US, China is currently $40 Trillion + in debt, borrowed more than double the US has in the time frame since 2008, China will implode long before 2032, China also can’t sustain massive amounts of debt over the long term like the US can, the only reason China has grown so fast (on paper) is because they borrow huge amounts and build stuff nobody can afford to live in, hence dozens and dozens of empty ghost cities, building things like cities, railways, airports etc, is the fastest way to grow your GDP, but pointless as most of that infrastructure lies unused and rusting/rotting away... All that’s left at the end is one huge steaming pile of toxic debt.
The Chinese may have aspirations of taking over Africa for agricultural and mining prospects.
