Taiwan has a great frequent interaction with China. Because of individual political policy and without judicial cooperation, many problems such as transnational crimes are aroused. In order to prevent the cross boarder crime and effectively proceed criminal suit in cross- strait, the third Jiang-Chang conference officially signed the contract ¡§Cross- strait cooperation for eliminating crime and agreement of judicial cooperation¡¨in Nanjing on 4/26 in 2009. The agreement made effect on 6/25 in the same year and turned a new leaf for the across- strait cooperation to reduce the crime. According to the agreement, the Cross-strait agrees to support in civil affairs and criminal domain, taking the measure to strike the crime in tune with the emphasis on kidnapping, firearms, drugs, population business and significant cross-strait criminal organization. Deception crime is part of the economic crimes and cross-strait deception crime has run wild in recent years. Hence the topic for the research is cross- strait deception crime. The research is aimed at signing the cross-strait agreement afterward and chooses three single cases on cross-strait cooperation to strike organization of telecommunication deception. On the other hand, supported by the questionnaire from similar cases that Taiwan police investigated, the research can point out the dilemma in eliminating guilt that both sides are faced with. At last, cross-strait police can propose feasible mode of investigating cooperation for striking cross-strait guilt by trying to erect the communication, exchange the information, investigate the crime evidence, repatriate the crime, and wipe out the crime together and the data can be provided for coherent units and follow up research. For the cross-strait cooperation for eliminating crime had made effect, the cross-strait deception organization had escaped from cross- strait to Southeast Asia. In the future, it is possible that the organization will expand to other countries and deceive people in cross-strait, and such situation makes police from cross- strait should inevitably be faced with the challenge of cross- strait and else in 21 century. In other words, except for highly intensive cross- strait cooperation, we must need to cooperate with the third country. Under the globalized structure, the research exerts the viewpoints and characteristics of Global Government and puts emphasis on ¡§Low politic, high function¡¨ cooperation to establish and integrate a cross- strait cooperation platform. The research proposes the strategy of cross- strait cooperation for reducing the crime and then hopes to positively come up with the solution for cross- strait deception crime to defend the safety of people from cross- strait.
