It seems that the Taiwanese EFL learners are using besides to mean also, as in this example on the Wikipedia article for Demographics of Taiwan, which, from the way it has been written, seems like it was probably written by a Taiwanese writer:
Besides, there are People from each Area of mainland China, Hong Kong and Macao residents, and Nationals without registered household in the Taiwan Area.
My question is, is this usage wrong? Instead, should the speakers be using something like: "In addition, there are people from each area of mainland China...." or "Moreover, there are people from each area of mainland China....".
My experience with the use of besides, as a native American speaker of English has been only when only providing additional reasons for justifying why nott to do something or providing additional negative reasons for not doing something. For example:
Speaker A: Why don't we go for beers at Carnegies tonight?
Speaker B: Not tonight, I've got to get up early tomorrow. Besides, I'm short on cash and won't get paid until next week.
Have I got this all wrong and, unbeknownst to me, are Tawanese English speakers really using besides correctly here to mean also, as shown in the Wikipedia article above?
