Philippine President Rodrigo Duterte has warned President Barack Obama not to question him about extrajudicial killings, or "son of a bitch I will swear at you" when they meet in Laos during a regional summit.
Duterte said Monday before flying to Laos that he is a leader of a sovereign country and is answerable only to the Filipino people.
He said Obama must be respectful and not just throw questions at him, or else, "son of a bitch, I will swear at you in that forum."
Duterte was answering a reporter's question about how he intends to explain the extrajudicial killings in the Philippines to Obama. More than 2,000 suspected drug pushers and users have been killed since Duterte launched a war on drugs after taking office on June 30.
Obama says he's asked staff to see if meeting with Philippine president would still be 'productive'.
