If that were true, when the Portuguese and Spaniards got to tne new world 90% of the people would have died recently of disease.
Those chinese ships were small floating cities and disease would have spread throughout the continent.

That post Portuguese/Spanish contact native American populations were annihilated by disease is now well established fact. That again argues against earlier Chinese contact.
Conveniently formulated historic fact absolving settlers IMO. Apropo to topic.
Convincing argument from indigenous is that indigenous in NA didn't get wiped out "because of" disease, worst historic pandemics wipe out like 50% of population over ~10 years before some sort of immunity kicks into population and gen pop rebuilds a few generations after that. Indigenous NA got wiped due to generations of increased deprivation enforced by settlers over 100+ years that made them suspectible to disease/fatality. It's like how malaria, dysentery, starvation was primary cause of death in prison camps, but really it's the fact that prison camp conditions allowed those diseases to spread in enviroment of artificially sustained deprivation.
90% population wipes over multipe generations isn't how disease operates, it's not natural epidemiologic behavior on continental scale. 90% population wipes happens because of coordinated genocide over generations across continent, blaming "contact" and "disease" is deflection. Hence if prevous visitors (can be whoever) didn't stick around for 100 years to coordinate a genocide, the indigenous people would still be around to greet Portugese/Spaniards, because they would have had ~100 years to recover/rebuild from whatever contact disease from prior meeting.
I'm sorry but contact alone with people from Eurasia or Africa would have innevitably almost wiped out native american populations.
I don't think this is even debatable.
So yes, IMO it's completely debatable 90% of population would STILL be wiped out after 100 years in event of an earlier, pre Columbian exchange where new disease is introduced to the continent. Because unless those visitors stuck around and active took effort to genocide the locals, but using disease as a weapon AND creating conditions where disease can proliferate without response, local population would recover after multiple generations (european population took ~80 years to recover from black death).
You write way too much for too little information.
Why take an account from an author of dubious qualifications and veracity seriously if the most significant evidence of such an encounter is entirely lacking?
Your reading comprehension is severely lacking.
I mean the next step for the Chinese is to take such bullshit as true and start laying claim to the Americas.
Clear now?
