President Rodrigo Duterte on Friday continued to lash out at former Colombian President Cesar Gaviria, who earlier criticized his campaign against illegal drugs.
"Itong tontong Presidente ng -- he must be stupid. Itong ex-president ng Colombia, sabi niya, 'Duterte is committing the same mistake.' We cannot never be in the same mistake because I am not stupid, you are," Duterte told a business forum in Davao City.
"Nagyayabang naman itong former President that I have committed the same mistake. That is only possible Mr. Ex-President if I am as stupid as you, I said. But unfortunately I am not," he added.
In an opinion piece in the New York Times, Gaviria warned that Duterte is committing his mistake by taking a tough stance against drugs.
He suggested that instead of using force against drug users and traffickers, Duterte should start looking at the drug situation in the country as a social problem.
Gaviria was president of Colombia at the height of the notoriety of slain drug kingpin Pablo Escobar, during which his country was one of the primary suppliers of cocaine to the world. Gaviria's heavy-handed approach to the problem, he admitted, has done more harm than good.
But in his speech, Duterte, who had previously called Gaviria an "idiot," pointed out that Colombia got the help of United States in its anti-drug war.
"Kasi ang Amerika, nagbuhos ng bilyon because they were flooding America with...All the supplies of cocaine and heroin came from that country.
Anong tinulong ng America dito except to recommend for my prosecution in the International Court of Justice, International Criminal Court?" he added.
Duterte's campaign against illegal drugs has been blamed for the deaths of over 7,000 people, most of them drug suspects.
