Colombia and Mexico have negotiated an extradition agreement that will allow nationals of each country to be send to stand trial in the other country.
The previous treaty only allowed for the extradition of foreigners between the countries.
The two presidents will sign the treaty when Colombia's leader Juan Manuel Santos visits Mexico in August
Colombia's Interior Minister German Vargas Lleras welcomed the move, calling it a "fundamental advance in the struggle against crime."
He said that "No Colombian or Mexican should expect to receive protection from their state when they commit crimes abroad."
As InSight Crime has noted, Mexican drug trafficking organizations such as the Sinaloa Cartel have been expanding their presence in Colombia in recent years.
