The emigration of labor force from Myanmar to Thailand has a long history and many of them have settled their families permanently in Thai communities over century. Once the Burmese labors came to Thailand as illegal workers, their descendants born in Thailand by no mean became stateless people without citizenship. Because of their statelessness, the second generation of Burmese workers has been identified as potential victims of human trafficking. Therefore, research project on human trafficking of the second generation of Burmese workers was aimed to investigate number of victims, process of victimization, and nature of human trafficking movement. Proper policy to suppress human trafficking problem was also recommended in the findings of study. Areas of study embrace communities where majority of second generation of Burmese workers has been inhabiting which include Mae Sai district in Chiang Rai province, Mae Sod district in Tak province, Muang district in Samut Sakorn province, and Muang district in Ranong province. Sources of information are mainly from victims themselves, government officers, and non-government organizations’ workers. Annual reports and official documents are also parts of sources of information. Results of study revealed that once the highlight of the study was on the second generation, therefore victims of human trafficking found were mostly related to children such child-sex abuse, child labor both in industrial and service sectors, and forced marriage. Due to the fact that most of human trafficking cases were conspired by many partners in crime which included their parents and offenders. Many parents of victims thought that if they wanted to reduce their family cost of living and also earn some extra income, they could do so by selling their children to the brokers who lived in their communities. By doing so, the parents will receive monthly income from the masters of their children in exchange. Normally there was no dispute if money was transferred regularly to their parents. But whenever, there was no money given to their parents, they will decide to bring their cases to inform non-government organizations with allegation that their children were human trafficked. But in fact all these happened are conspiracy of all partners. Therefore all information obtained from them is not reliable and very limited. Since human trafficking in the study is a type of organized crime against the second generation of Burmese workers immigrating to Thailand, therefore there are at least 3 factors identified as causes of problem. Most of the victims’ families are poor and have to feed many children. The way they do is to earn more income and save their living cost. By selling their children to the brokers they receive extra money and at the same time they can reduce cost of living. However, poverty is not an only cause of selling their children if they have no culture of passing the burden to their children. With an expectation that their children have to support their parents to get a better life, they negotiate with local brokers or their relatives who get involved in human trafficking business and their children were sold to work as sex workers, beggars, flower selling, and sometimes to marry to an unknown husband. Last factor that leads to human trafficking business is to have connection with brokers and people concerned. As an organized crime, human trafficking activity works well in trustful atmosphere with cooperation of people concerned like masters, brokers, and government officers. In order to suppress human trafficking, the authorities concerned face with many barriers, for instance a complexity of prevention and suppression of human trafficking law, and a problem of law enforcement. At the stage of enforcement, most of officers are in lack of knowledge and experiences and they sometimes feel reluctant to apply human trafficking law in effect. Some officers also take advantage from this situation by receiving bribe from the crime makers. Moreover, when government of the United State of America would like to ensure that all countries give a full hand of cooperation against human trafficking crime, in order to show international community that Thailand has no human trafficking crime, some provinces conceal cases of human trafficking in their areas. Another obstacle to suppress the crime is an inadequacy of cooperation from their parents since they are afraid that they might be threatened by crime makers. Resolution of the problem may come from a proper government policy on human right of the second generation of Burmese workers in Thailand. If they can not access to their rights in education, working permission, and others, then they are in risk to be victims of human trafficking. Another method of prevention is to identify a risk group in communities and how we can hand them protection both at individual and family levels. Mitigation of vulnerability in 3 factors namely poverty, undesirable culture, and vicious connection will be of help to reduce risk. Last but not least, international cooperation between countries of origin, countries of transit, and countries of destination certainly increases efficiency of human trafficking suppression.
