Not sure why they put a Swatstika on the can. I looked it up, it's a Taiwanese company. Maybe some of the company owners are very religious and thought it was appropriate to put it on the can as good luck or positive message to it's customers?

I once had some business with a Taiwanese company and each time they sent a pdf file with their promotions, the first page was a quote from the bible with some extra text around it (don't know what, I generally skipped that page). So I know of at least one company that was including the owner's religion in the business. Not sure if this is something that happens often or not.

I'm also not saying this is definitely religion related, but it is the first explanation I can think of.

Edit: I did some more research. Apparantly some Taiwanese restaurants put a swastika symbol out to show they're a vegetarian restaurant. As it is (among other things) a buddhist symbol and some buddhist don't eat meat. So as this is a vegetarian sauce, the swastika is probably just symbolizing that it's vegetarian.
