This a very exclusive field, but the answer is yes, there are.
Personally, I know of one firm that provides customized investment advise to US expatriates in Thailand and throughout Southeast Asia:
Creveling & Creveling Private Wealth Advisory 3 Sukhumvit Soi 30 Khlong Toey, Bangkok 10110 Tel: +66 2 661-2716 Fax: +66 2 661-2724 www.crevelingandcreveling.com
It is likely that they know of firms similar to theirs that provide this same service to international clients in your area - Europe and China. Or, it is possible that they may be able to assist you directly. It is probably at least worth a call to find out.
Best of luck with this!

Keats Connelly (http://www.keatsconnelly.com) is a US-based wealth management firm with a focus on cross-border planning for the US-Canada crowd, but I'm betting they receive inquiries like yours and may be able to refer you to a US firm or two that serves clients in Europe and China. Might be worth a contact to them.
All the best!
