The prime minister's brief meeting with Duterte took place before Trudeau delivered a speech to members of the Association of Southeast Asian Nations in a bid for Canada to eventually join its exclusive, influential circles that focus on security in the Asia-Pacific.
On Sunday, he tried to have it both ways, saying he believes both the USA intelligence agencies when they say Russia meddled and Russian President Vladimir Putin's sincerity in claiming that his country did not.
Duterte thanked the Russian President for the 5,000 high-powered firearms that Russia donated in October, for the Philippines' counterterrorism efforts. "And also I think Mr. Trump is, for whatever reason, either intimidated by Mr. Putin, afraid of what he could do or what might come out as a result of these investigations", Brennan said.
'When I was a teenager, I would go in and out of jail. The next day Trump and Duterte meet one on one.
As regards the South China Sea, the official said there has been a "very clear" and "consistent message" from Trump on freedom of navigation in the South China Sea.
But ISIS's hold on Iraq and Syria continues to crumble in recent months, so the group has encouraged new recruits to travel to the Philippines and other countries instead - and Secretary of State Rex Tillerson said in August that some fighters in the Middle East have traveled to the country.
In Danang, Duterte also targeted the United Nations' special rapporteur on extrajudicial killings, Agnes Callamard, who has been a frequent critic of the drug war. "It was just over a look", Agence France Presse quoted him as saying.
Before boarding Air Force One en route back to Washington on Tuesday, Trump spoke briefly with reporters.
Since Duterte's inauguration previous year, police and affiliated death squads have summarily executed more than 8,000 suspected drug users.
He said Duterte told Putin about the country's "very bad experience" with two of the three U.S. second-hand helicopters that crashed.
What they are not expected to do is talk seriously about human rights. Bishop had previously criticised the drug war.
Duterte won last year's presidential elections after promising to eradicate illegal drugs with an unprecedented crackdown that would see up to 100,000 people killed.
"Forget what they say, those human rights (activists)". Human rights groups believe the victim total is far higher, perhaps closer to 9,000.
"On the grounds of what both Duterte and Trump (have) done and (are) continuously doing, it is not that they do not understand the concept of human and people's rights, it is that they just do not care", Palabay said in a statement.
Though the Trump administration has yet to propose an adequate response to its crisis - declaring a national emergency and failing to put any new spending behind the order is clearly insufficient - at least it recognises that using the police to kill dealers and users is not a solution.
