There is no difference in the content of the books between the editions. The Asian edition is priced to be competitive in that corner of the market, and is reflected in the size, weight and slightly lower print and binding quality of the book. Neither book contains a CD. The non-Asian book contains a 30-day subscription to one complete online mock exam (at
http://exams.garnerpress.com); for logistical reasons, the Asian edition of the book does not come with this subscription, though a subscription can be purchased on the exams website I just mentioned.
Hope that helps.
