The difference between legal repatriation and extradition

Repatriation is extradition without a treaty, that is, it takes place in two countries that have not signed an extradition treaty. China and Colombia have not signed an extradition treaty, so it belongs to repatriation. "Repatriation" is an informal form of international assistance, which is mainly used to send refugees and illegal immigrants back to their countries of nationality. Compared with extradition, repatriation is relatively simple in procedure. Under normal circumstances, it is only necessary to prove that the suspect has no legal residence status and has left the country illegally. Repatriation can be used as an alternative to extradition, because it has the same objective result as extradition and is sometimes called "de facto extradition".

Extradition refers to the act of a country handing over a person accused or convicted in its territory to another country for trial or punishment at the request of that country. It is a form of criminal judicial assistance between countries.

There is an important condition for extradition, which must meet the requirement that both the requesting country and the requested country constitute crimes, that is, the so-called double criminality. Once the extradition request is accepted, it means that the requested country will take compulsory measures against the requested person and hand him over to the country where criminal prosecution or punishment is carried out by compulsory means.
