Regarding laws and regulations on waste processing and water treatment the Vietnamese government has issued decrees which contain the standards and requirements companies have to comply with. Although these standards are at a relatively high level, Vietnam still has to face environmental challenges due to infringement. The reasons for that are mostly not accomplishable claims, a lack of enforcement and a non-sufficient budget.
