贪官逃往国外的主要原因是逃避打击及防止外逃的相关制度不完善、管理不到位、协调不一致等主客观因素造成的。遏制贪官外逃应积极推进反腐败制度建设,加大对贪官的监控力度,扩大国际警务合作。 The main reason for the corrupt officials to flee to other countries is the subjective and objective factors such as the imperfect system of escape from fighting and the prevention of flight, the inadequate management and the inconsistent coordination. To curb the flight of corrupt officials, we should actively promote the building of an anti-corruption system, step up the monitoring and control of corrupt officials and expand international policing cooperation.
