“我认为每个国家都想要保护它自己的国家安全，保护它的有价值的技术，所以毫无疑问，当你看到这些技术上的进步时，将会有竞争以及对于保护这些非常有价值的重要资产的关切。我认为你没办法阻止紧张态势，但是你必须认识到每个国家都有权利来保护他们自己的安全。”2019年3月8日，周五，布兰斯塔德大使接受彭博社的采访 

“I think every country wants to protect its own national security, and protect its valuable technology, so it’s no doubt, as you see these advancements in technology, that there is going to be competition and concern about protecting those very valuable important assets.  I don’t think you are going to be able to prevent tension, but you have to recognize that every country has a right to protect their own security.” Ambassador Branstad, interview with Bloomberg, Friday, March 8, 2019
