The meeting comes just days after Duterte used explosive language about Obama, forcing Obama to abruptly postpone a formal meeting the two had scheduled during his visit to the region.
The Filipino president called Obama a “son of a b----” on Monday and, while speaking to reporters, warned Obama not to question his policy of extrajudicial killings. Obama, in turn, called Duterte "a colorful guy" and signaled that the bi-lateral, face-to-face meeting would be canceled.
Duterte expressed regret for his word choice the next day and thanked Obama, in a written statement, for the continued support of his country.
Obama’s visit to Laos follows a stop in China, where he attended the G-20 summit of global economic powers. He is scheduled to depart Laos on Thursday.
