The Iowa connection apparently means a lot to Xi. If it was his first trip out of China, it would probably have made a major impact, especially 30 years ago. And it is probably a good thing that his first exposure to the U.S. was the heartland, not New York, DC, or some crazy place in California.
I am a native Iowan. I speak English. Who the hell are you? Some Egyptian monolith? Hablo Espanol?
Former Iowa Governor Terry Branstad was one of the US counterparts to Xi during that Iowa trip and apparantly they became friendly and have maintained that through the years. Xi is not running China and Branstad was just nominated by Trump to be Ambassador to China but he has yet to be confirmed.
