They stopped because the imperial court's advisors foresaw the colonies becoming another powerful entity and didn't want to end up like Britain where you eventually become the junior partner of your former colony like USA today, South east Asia was much closer and any overtly ambitious Chinese merchant guild there could be quickly dealt with it's also why Chinese withdrew from central Asia the generals stationed there were proving to be too difficult for the emperor to control due to distance and terrains involved.

Cool alt history analysis.
Where are these famous advanced Chinese ships? How and where were they built etc`?
This is a good analysis. Well done.
Ancient International Trade existed. Then there was the inquisition
There was no such thing as "China" back then. Different dynasties and tribes.
True, I was just generalizing based off the main dynasty in control then
