However, Duterte called out “I’m the President of a sovereign state, and we have long ceased to be a colony’. He then went ahead to call Obama ‘son of a whore’.
Obama said, ‘Clearly he’s a colorful guy. I always want to make sure if I’m having a meeting its productive’.
Duterte has come under criticism for his disregard for human rights in his fight against the illegal drug trade as policemen have carried out thousands of extrajudicial killings.
However Duterte has now said he regrets the remark.
"While the immediate cause was my strong comments to certain press questions that elicited concern and distress, we also regret that it came across as a personal attack on the US president," a statement by his office said.
