The thing with corruption in Vietnam is that it is so entrenched in the country. There are swathes of people out there saying they are fighting corruption, put they are merely paying lip service. Most of these Project Managers and Procurement Officers you talk about are extremely corrupt. To the point they will not allocate a project to those who pitch for World Bank work unless the Project Manager is paid off etc. Many people seem to know here that the World Bank is very corrupt. The World Bank needs to look inside its own organisation and fix the rampant corruption within the WB, before it can preach to the rest of the country.
