Structure

Small group of criminals, ''băng nhóm'', has simple structure. It is organized loosely with a small number of members. The leader is called ''đại ca'' or ''băng trưởng''. They act aggressively and mostly commit crimes such as murder, robbery, theft, and fraud. These small groups may band together to form a larger syndicate or find protectorate from an already existed one. A larger criminal syndicate, ''băng đảng'', has a clearer, more sustainable organizational structure with long-term operational goals. The leadership can have one or multiple people, but there is one individual at the top known as ''trùm''. Below them is the command level with people who would be in charge of smaller groups within the syndicate. Ordinary members, known as ''đàn em'', are those who directly carry out criminal acts, as well as all tasks assigned by the leaders. For example, during the 1960s in

They mainly involve in crimes against their own community including murder, extortion, robbery and petty drug dealing, with standover and extortion being the most common. Vietnamese criminal organizations are known to organize heroin shipments, either independently of or in association with established Chinese heroin trafficking operations. An increasing amount of heroin coming to Australia appears to have been transhipped through Vietnam. Australian polices have significant difficulties in counteracting Vietnamese organised crime due to a lack of Vietnamese police officers, consequent language barriers, and a common mistrust of government agencies by migrants from Vietnam.
