Mfs seem to have forgotten that Chinese GDP PPP is already higher than the US
That was from the IMF which is owned by the US... I don't think they'd report it if there was any way they could spin it.
It looks like China overtook the US in 2017 for GDP PPP

Also I was wrong, it looks like the current numbers are China 19 trillion, US 15.5 trillion but I'm pretty sure I heard those original numbers somewhere recently
