Surpass in nominal GDP? but such measurement is dependent on the U.S. currency, which is the defacto world reserved currency. When the dollar inflates/appreciates its value up goes it's GDP while the countries of the world suffers and are affected, China is of no exception. Is it not the case?
A lot of these writings and prognostications of China winning, China collapsing are being done majority of the time, by Western-China watchers, both the doomers/gloomers and boomers. China never publicly expressed that their intended desire is to surpass America's nominal GDP by such a date in x,y,z when in fact, by the time managed to surpass U.S. GDP via PPP calculation the general consensus in China's leadership was of alarm, since they were quite adept and sensitive to how the Americans would perceive such unwelcome news. The ego, and butthurt from the Americans would be unbearable as we have all witnessed these many years.
Western publications, build up their China strawman, both pros and cons, then they busily argue with, for, and against themselves deconstructing, explaining, extrapolating their fallacious arguments without actually giving a flying 2 bits what the actual Chinese people both from within and without the government.
Western mindset is quite extraordinary when it comes to inventing fiction.
