The IMF has
the April 2024 edition of its World Economic Outlook publication, which extends the horizon of its economic projections to 2029.
At current exchange rates, the IMF projects China's GDP in 2029 to be USD $24.8tn compared to USA's projected GDP of $35tn. That is to say, the projection is for China's GDP in 2029 to be 71% of USA's GDP, up from 65% in 2023.
This represents a downgrade from the previous October 2023 projection (72% in 2028), which was a significant downgrade from the April 2023 projection (85% in 2028) which in turn was a significant downgrade from the October 2022 projection (93% in 2027).
In PPP terms, the IMF projects China's GDP in 2029 to be $46.3tn or 132% of USA's projected GDP, up from 120% in 2023 but down from 134% in 2028 as projected in the October 2023 publication.
