The Global Economy In 2023

Heading into 2023, there is much economic uncertainty. Many experts are anticipating a brief recession, although opinions differ on the definition of “brief”.

Some experts believe that China will buck the trend of economic downturn. If this prediction comes true, the country could own an even larger slice of the global GDP pie in the near future.
