Oops, totally missed this thread!
If you mean swashbuckling as in going around conquering people.... thats not what China's sea voyages were for.
Nope, I didn't mean going around and conquering - I meant they were not inspired with a spirit of exploration, trade, and good ol' fashioned greed - for example, the famous example of Christopher who attmpted to make a very long and crazy voyage around the flat world to find a way to India for spice trading; Magellan did go around the entire planet for exploration and what-not, the Dutch landed on Taiwan to set up trading for all sorts of spices and goods.
>phew< (taking a breath)
I guess the point is that I think western civilizations were somewhat racing to uncover riches and make discoveries all around the world - which is what makes them different from the Chinese, who were far less concerned with exploration, and far-flung sailing trips, especially during it's times of instability and invasion.
Of course, there is a possibility of it, and anything could have happened, so I would never rule it out either.
