Former Governor Branstad developed a good relationship with China by selling them soybeans. Many dignitaries from China toured some of the same farms I did. Trump appointed Branstad as diplomat to China because of that. Reynolds is continuing that relationship in order to continue selling Iowa (and national) crops to China. Normally, that would be sound foreign policy.
This isn't proof that she's a sellout. She is actually trying to do what helps Iowa. Feel free to dig deeper, but understand there are very good reasons for a relationship there. If you can find anything inappropriate, I want to know.
