I think a good part of the answer lies in your first inference.
Specifically, I don't think the teaching and learning of English is particularly valued in China, academically speaking. Most of the students don't see the need for it and virtually all university administrators deeply resent being forced to hire foreign teachers to meet their national "exposure to a native speaker" requirement. Throughout the entire country, the students who get assigned to English as a major are the ones who scored too poorly on the Gao Kao (national college entrance) exam to receive their top choices.
When I was teaching oral English, I would receive my teaching schedule and textbooks anywhere from one to two weeks before the beginning of classes. Despite my years of experience in the classroom and my popularity with the students, I came very close to being terminated (not having my contract renewed) because I allowed my skin to become too dark during one Golden Week holiday (I had spent the entire week tanning at the beach). I was specifically ordered to stay out of the sun "or else." It was then that I realized the cold hard truth: Despite whatever qualifications and experience I had, I was teaching at this school because I looked the part. There was really no point in deluding myself any further that I was teaching at this university because I was considered special or particularly valued as a result of what I brought to the classroom.
Of course, the situation is radically different today and I don't think it has anything to do with a difference between the two universities: The difference is that I am now teaching in my field again. They need a Western professor to teach medical psychology, psychiatry, and statistics. I am (for the first time in six years) actually consulted three months in advance about not only what I will be teaching but am also given the courtesy of selecting the specific days and class periods. Although this was all par for the course back in the United States, in China, it's like I've died and gone to heaven.
Having just written all of this, I don't think the multilayered and profoundly complex Chinese bureaucracy is the most efficient system in the world. There are many times that even the Chinese professors don't know what is happening until the very last minute. They too are subjected to unexplained last minute changes in schedules and meetings, not just foreigners. The big difference, of course, is that they have learned how to expect the unexpected (and not ask questions) while we, instead, wave our SAFEA contracts in the air, yelling "not fair."
A good friend of mine back in Haikou, a Chinese colleague, once told me: "In China, if you don't have patience, you have nothing."
I think he was right.
