Hi,
I understand what you mean, I can make and IP list just according to your needs, we can start from a the major IP address blocks for China, Hong Kong and Taiwan, and then filter them asking each IP if it's from US or not or we can filter them from know serious black lists.
If you can give me more information about what you want, why do you need it or what problems have you experienced regarding to this IPs, I can create a better filter for you, and then provide you the best list you can have, and also I can provide you the script so you will be able to generate a updated list anytime for free.
Think about it and feel free to contact me anytime, have a great day.
