Fair enough, I will fix this one way or another. Thank you for your patience. (Just out of curiosity, why do you care about this enough to put so much effort into persuading me? Surely this is not the most destructive bit of misinformation floating around on the internet?)

P.S. I decided to actually look into the actual fact of the matter, and it appears Gibbs's claim may actually have some merit:

https://www.loc.gov/collections/railroad-maps-1828-to-1900/a...

"[The] chief promoter of a transcontinental railroad was Asa Whitney, a New York merchant active in the China trade who was obsessed with the idea of a railroad to the Pacific. In January 1845 he petitioned Congress for a charter and grant of a sixty-mile strip through the public domain to help finance construction." [Emphasis added]

The article doesn't specifically say that China was the principal motivation, but in 1845, before the discovery of gold in California, there weren't many other reasons to build a transcontinental railway. And since the railroad didn't actually get built until long after the gold rush was well underway, the actual motivation is probably a mix of different factors. But given Whitney's role, the idea that China was a factor seems like it could turn out to be defensible after all.
