Three days after, during a testimonial dinner in San Juan, Duterte asked former President Fidel Ramos to lead the Philippine envoy to Beijing for bilateral negotiations with China over the disputes.
In July 2016, Duterte accused the United Kingdom and the United States of importing terrorism to the Middle East through its interventions, saying: "The U.S. destroyed the Middle East. ... Great Britain and the U.S. will not admit that they forced their way to Iraq and killed Saddam. Look at Iraq now. Look what happened to Libya. Look what happened to Syria."
9月東盟峰會甚至屌鳩Obma係「Son of a whore」，要求美軍撤出菲律賓
At the 2016 ASEAN Summit, Duterte and U.S. President Barack Obama planned to meet with each other. The United States said that President Obama planned to discuss the 2,400 Filipinos who died during Duterte's war on drugs. Duterte criticized the planned topic of the meeting, saying, "I am no American puppet. I am the president of a sovereign country and I am not answerable to anyone except the Filipino people. You must be respectful. Do not just throw away questions and statements. Son of a whore, I will curse you in that forum." The vulgar insult prompted the White House to cancel the meeting instead.
On September 12, 2016, Duterte said that he is "not a fan of the Americans" and that he wants to "reorient" foreign policy with the United States. He requested that U.S. forces in Mindanao should leave the Philippines, specifically those who are part of the Operation Enduring Freedom, saying that it would "inflame the situation with the Abu Sayyaf".
In October 2016, Duterte continued his tirade against the US and the European Union saying in Tagalog that "Mr. Obama, you can go to hell. EU, better choose purgatory. Hell is already full. Why should I be afraid of you?"
On October 12, Duterte declared his intention to terminate joint US–Philippine naval patrols in the South China Sea, which he believes could needlessly antagonize China.
