China may now never take the US's crown as the world's largest economy

• China may now never become the world's largest economy, according to Bloomberg Economics.
• Forecasters expect its GDP to briefly pass the US's in the mid-2040s, before "falling back behind".
• Beijing has struggled to revive growth and shore up its crisis-hit property sector this year.

China's struggles to revive growth and shore up its crisis-laden property market this year mean it's unlikely to ever permanently take the US's crown as the world's largest economy, according to one recent forecast.
