The so-called Huawei/Meng Wanzhou case is an acute example of the application of unilateral sanctions in the field of inter-state criminal cooperation. It also illustrates the struggle for the status of world’s leading power between the USA and China. Meng Wanzhou is the chief financial officer of Huawei Technologies and daughter of the founder of this Chinese Telecom giant. She is accused of having put a US bank in legal jeopardy by concealing from them that a subsidiary of Huawei was trying to sell US technology to Iran in violation of American sanctions. Arrested by Canadian authorities on 1 December 2018 at the request of the United States, she has been living since in Vancouver pending her extradition decision. This chapter shows how and to what extent the individual rights of foreign nationals criminally sanctioned for violations of extraterritorial law could be protected by extradition law and by human rights.
