I have entertained some senior bankers from CCB,NCB etc, they claims that they have much better expertise in consumer/corporate portfolio credit risk review and approval.The areas they are looking to improve immediately are Market Risk Aanalytics and reporting.
If you are focusing on quantitative side of credit risk such as modelling,it is good in future, guess this is the area you are referring to. but do not know when China bankers will fully appreciate and adopt it. Albeit future is promising, you must be the type of quantz person.
