I work at a large research university in Australia. At UG level most of our students are local, but at PhD level most of our students come from other countries with a lot of them being Chinese. Education is a major export of Australia.
Like any large group, there are good and bad, less skilled and more skilled. In general I find the fresh Chinese students in science and engineering to have a lot of good basic knowledge, but not much ability to think for themselves. They want to be told how to do everything and if given two differing opinions, they don't critically evaluate the situation for themselves rather the more important person must be right.
Anyway we demand that they design their own experiments, with our help and training. Then write it up, including safety. Then perform it, with snap inspections. Then trouble shoot it and evolve it. They all hate it at first, it's almost torture to them, especially the snap inspections. "Why did you write up all these safety features, when you are not doing any of them?" "if you don't need them, then don't add them to your written plan, but if you do need them, then make sure you do them". They often start out saying what they think you want to hear, but doing what they want to do.
Anyway three years later, they are completely different people. Solid independent thinkers, with good planning skills and the ability to say what they do and do what they say. Excellent scientists and engineers, and often a good friend. Half of them want to stay in Australia, but I hear those that go back to China quickly find themselves in senior positions.
I'm sure this is happening all around the world, and at some stage China will start inventing rather then just copying.
