The most effective means to combat transnational and corruption crimes is to cooperate internationallyin tracing fugitives and recovering stolen assets. In order to deploy cooperation better and make it legal, Chinahas acceded to several international conventions, such as the United Nations convention against corruptionand the United Nations convention against transnational organized crime. Relevant extradition treaties andagreements on criminal judicial assistance have also been signed with many countries. These multilateral andmultilateral treaties provide a legal basis for international cooperation in the pursuit of fugitives and assetsabroad, but there are still many problems. These problems are the legal obstacles for China to effectively carryout international cooperation in the pursuit of fugitives and assets. We can strengthen the signing of bilateral andmultilateral treaties. In line with international legislation, perfect our extradition system; Make clear the subjectof asset recovery and draw lessons from the civil confiscation system and asset sharing system in developedcountries. On the basis of the newly promulgated international criminal judicial assistance law, we will furtherimprove our international cooperation system of chasing fugitives and recovering stolen assets.
