"I never think of hate, because hate belongs to that era", said the victim, who requested anonymity. Duterte asked. "I am no American puppet".
"I am a president of a sovereign state and we have long ceased to be a colony".
Speaking to a reporter, the president also exclaimed "putang ina" - a Tagalog phrase that roughly translates to "son of a whore", but is often used in a manner equivalent to "crap" or "shit" in a manner similar to the Spanish phrase hijo de puta.
The meeting between Obama and Duterte was rescheduled and will not occur this week while the two leaders are in Laos for the Association of Southeast Asian Nations summit.
Following the cancellation of the meeting, President Duterte said on Tuesday that he regretted his comments about President Obama.
He also said Obama would likely hold an informal discussion with Duterte in Laos on Wednesday or Thursday, though formal talks remained off the table.
Obama late on Monday arrived in Vientiane for the first visit by a sitting USA president to Laos, where he wants to begin to address the legacy of USA bombing during the Vietnam War.
"They first need to understand the problems that my country faces before they talk about human rights", said Détente before he continued with making an infamous comment about the U.S. president. After Duterte's remarks, Obama instead made plans to meet with South Korean President Park Geun-hye, Reuters reports, during which the response to North Korea's latest missile tests were expected to be part of discussions.
It's being said that Duterte's statement was aimed at avoiding a meeting with Obama in order to evade questions on the extrajudicial killings. 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.
Despite the lack of apology, the bomb victim said he hopes his nation and the United States can now move forward, and that Obama will press the Lao government to allow more freedom inside his country.
Obama showed that he would not be intimidated by Duterte, saying he would "undoubtedly" still bring up human rights and due process concerns "if and when" the two do meet. "Son of a whore, I will curse you in that forum".
The US provides hundreds of millions of dollars in annual assistance to the Philippine military.
Obama said the latest round of ballistic missile launches were "provocations" that flouted worldwide law and would only lead to further isolation.
The Philippines, Vietnam, Malaysia, Brunei and Taiwan also have competing claims to parts of the sea, but have watched China expand its presence by building artificial islands in key locations.
