US has more land area than China - if US population grows substantially, it'll be able to counter China's momentum [COMPACTIDEA]

China is attractive because of its size. China isn't very efficient yet, in the sense that its GDP-per-capita is quite low. US has slightly more land than China, but substantially less population [though substantially higher GDP-per-capita]. US has an opportunity to "contain" China by doubling its population. Double population will produce more and consume more and will massively increase the attractiveness of US as a market [and simultaneously lower the attractiveness of China, because total attractiveness is a zero-sum game]. US, no doubt, is already an attractive market due to its size and efficiency, but if US wants to lower China's increasing attractiveness, it must increase its own "size".
