Colombian President Gustavo Petro has campaigned in the United States for his new drug policy.
"If we implement land reform as agreed in the peace treaty, that would put a stop to drug production," Petro said after a working meeting with US Secretary of State Antony Blinken in Bogotá on Monday (local time).
Colombia can stop being a drug trafficking country by producing agriculturally and industrially.
Blinken said his country supports Petro's comprehensive approach to the fight against drug trafficking.
Colombia is the United States' most important ally in South America.
Decades of the war on drugs, billions of dollars in financial aid and a peace agreement with the guerrilla organization FARC in 2016, which was mainly financed by drug trafficking and protection money, have not been able to stop the large-scale cultivation of coca in Colombia .
Cocaine is made from coca.
Colombia is one of the largest producers of cocaine in the world, ahead of Peru and Bolivia;
much of the cocaine is smuggled into the United States.
After taking office in August, the new left-wing President Petro, a former guerrilla, announced that he would break new ground in the fight against drug trafficking.
In his first speech to the UN General Assembly, he caused a stir when he said, among other things, that the irrational war on drugs and the destruction of the Amazon showed humanity's failures.
