I tend to think that the policy is wrong - it is based on the desire to improve things on paper but not in reality. More generally, it is disappointing to see that so many things are decided by the money etc. but if this is what is behind these questions, one should at least approach them rationally.
A meaningful goal of these investments should be to create an environment in which many results are actually found on the Chinese territory and in which the leading scholars actually influence others in China, and I am afraid that this "trophy hunt" can't lead to such an outcome.
