Trump is slated to meet several times with Philippine President Rodrigo Duterte (doo-TEHR'-tay).
Trump says he'll have more to say about trade at the White House later this week.
Wrapping up his extensive tour of Asia, Trump hailed "tremendous amounts of work" on trade and said nations around the globe have been put on notice that the U.S. will demand improved trading conditions.
A spokesman for Duterte, however, said "there was no mention of human rights" and "no mention of extralegal killings".
President Donald Trump skipped the last few engagements of his Asia trip and left Secretary of State Rex Tillerson to sit in a meeting in his stead. "Human rights briefly came up in the context of the Philippines' fight against illegal drugs", Sanders said.
President Donald Trump is wrapping up his extensive trip to Asia with an worldwide summit and one-on-one meetings with global partners, including his Philippine host who is overseeing a bloody drug war.
Due to arrive in Washington late Tuesday night, the president said he will make major announcements on trade and North Korea on Wednesday at the White House.
"Terrorism and violent extremism endanger the peace, stability and security of our region because these threats know no boundaries", Duterte said, who last month declared victory over Islamic State-inspired militants in the southern Philippine city of Marawi.
While Prime Minister Shinzo Abe, the only foreign leader who visited Mr. Trump at Trump Tower before his inauguration in January, rolled out the red carpet for the president, journalists in Tokyo had mixed opinions about the Japan leg of the trip.
Trump announced on Twitter that he will be making a "major statement" when he returns to Washington.
More than 3,900 pushers and users have been killed in the war on drugs that Duterte declared when he took office past year.
Mr Trump has faced criticism for praising Mr Duterte during a phone call for the "great job" he was doing to counter illegal narcotics.
