http://www.gov.cn/english/laws/2005-09/22/content_68710.htmArticle 8 The request for extradition made by a foreign state to the People's Republic of China shall be rejected if:
(1) the person sought is a national of the People's Republic of China under the laws of the People's Republic of China;
Good research. But what makes you think these people are even Chinese? If they are scammers thay are using the 'China issue' as a barrier to extradition to put off investigators, it won't work. They are more likely in the West.
my point was that the US does not have unilateral jurisdiction here.
