"Tremendous amounts of work was done on trade".
Trump told reporters in Manila that the "fruits of our labor are going to be incredible".
Trump, who campaigned for office on a promise to tear up multilateral trade agreements that he said have harmed the USA, insisted during the almost two-week trip that multibillion-dollar deficits that favor US trading partners will be reduced to zero, and that trade overall must be fair and mutually beneficial.
Duterte seemed confident he had Trump's backing for his deadly war on drugs.
"It's not as if we are trigger happy", Duterte apparently told Trump. "Tremendous amounts of work was done on trade".
The comments came ahead of an Association of South-east Asian Nations (ASEAN) meeting in Manila, which starts on Sunday.
At APEC on Friday, Trump also said the United States will no longer "be taken advantage of" through trade agreements, but also called for mutually beneficial trade deals.
But most of all, Trump will have to tangle with the country's controversial president, Rodrigo Duterte, who has a reputation for filthy language, has faced charges of crimes for his drug war, and has claimed several times to have killed people himself.
Tomorrow, Trump and Duterte are expected to hold bilateral talks.
Press Secretary Sarah Huckabee Sanders blamed scheduling conflicts. I would say disgusting is putting it mildly.
Her readout appeared to conflict with the Filipino version of the meeting. There was no mention of extralegal killings.
Trump's relationship with Moscow has haunted the first year of his presidency, with key former aides under a United States investigation for alleged collaboration with the Kremlin.
"Foreign leaders should recognise that the fist. symbolises a purposeful attack by Duterte on rule of law that has inflicted a human rights calamity on thousands of Filipinos", Phelim Kine, Human Rights Watch deputy Asia director, told AFP.
Since Duterte took office 16 months ago, police say they have killed 3,967 people in the crackdown on illegal drugs. How much more now that I am president?'
Human rights group Karapatan said a meeting between Duterte and Trump on human rights will be "one big sick joke".
Trump will also meet with Prime Minister Narendra Modi of India, which plays a key role in the US vision of an Indo-Pacific region that attempts to de- emphasise China's influence. And he will meet with Australian Prime Minister Malcom Turnbull, with whom he had a contentious phone call this spring. Trump raved about his accomplishments on his five-nation journey, particularly on trade and on North Korea, which the White House has suggested may be designated a state sponsor of terror.
Trump was originally slated to depart Manila for Washington on Monday.
"It was not Trump who raised it. Trump never raised it, honestly", Roque said.
Trump's discussions will largely centre on trade and North Korea but he remains dogged by things he has said, and not said, about Russian Federation. "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. "And that really is a sign of respect, perhaps for me a little, but really for our country".
