President Barack Obama on Monday said he has asked his staff to assess whether it would be productive for him to meet with Philippine President Rodrigo Duterte. <br /> <br />This, after Duterte warned Obama not to question him about extrajudicial killings in his country. <br /> <br />Obama was asked at a news conference in China on Monday whether he intends to meet Duterte, as planned, at a gathering in Laos this week of the Association of Southeast Asian Nations. <br /> <br />Duterte said Obama should not question him about extrajudicial killings, or, as he put it, "son of a bitch, I will swear at you" when they meet in Laos. <br /> <br />Obama said he had heard about the comment and instructed his aides to determine whether it would still be productive to hold the face-to-face meeting. — Associated Press
