The potential there, but it needs time, and the relationship between the time decrease and required resources is quadratic, means cut back the development time from ten years to one require hundred times more resources now.Given that China has a $14-15 trillion real GDP, $5 billion or so in American IC fab gear is less than a rounding error (and SMIC could just unload the equipment to someone else).
That is BS US has to pay interest on those treasury bill it is not free money and support US consumer to buy more chinese product!. You rumbling about getting product for nothing is just not supported by reality . In 1975 Chinese GDP/capita is only $200 now is more like $10000 See what export economy does. The same thing with Korea, Japan, Taiwan, Singapore all of them follow the same prescription export their product!
USA Treasuries carry a -2% (MINUS) inflation corrected interest. If in the future the inflation go up then it will be even higher.
Yes, Japan, Korea examples showing how clever the USA to exploit other countries.
