it already is a big problem for US ... especially with Saudi Arabia and UAE joining ...apart from 3 of the worlds largest economies china India and Russia .. with potentially the 2 largest economies in SE Asia Indonesia and Thailand maybe joining soon
not sure when this was done ...china has been the no 1 country in PPPgdp terms since 2017 ... WTO uses PPP as it's a more accurate reflection of a countries wealth as opposed to GDP . Last I heard Russia had 4 th largest economy In Europe
