Well, it's anyone's guess what President Donald Trump has lurking up his sleeve after he hinted on Sunday to a "major" announcement on trade and even North Korea, upon his return from his 12-day, five country tour of Asia.
The meeting among the US president, Australian Prime Minister Malcolm Turnbull and Japanese Prime Minister Shinzo Abe signaled their growing concerns about China's power in the Indo-Pacific region - and the potential threat that North Korea poses to its neighbors.
"And it will be a very complete statement as to trade, as to North Korea, as to a lot of other things".
Trump also visited Japan, South Korea and China.
President Donald Trump is ignoring questions about human rights abuses as he meets with the president of the Philippines, Rodrigo Duterte (doo-TEHR'-tay), on the sidelines of an worldwide summit in Manila. Duterte says their bilateral meeting is not a press conference.
One of the leaders on his flank: Philippine President Rodrigo Duterte, who has overseen a bloody drug war that has featured extrajudicial killings. Spokeswoman Sarah Huckabee Sanders said human rights came up "briefly" in the context of the Philippines' fight against illegal drugs.
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.
In opening remarks before the 17 other leaders at the summit's plenary session, he called illegal drugs a menace that threaten "the very fabric of our society", without mentioning methods of the response. "But I only want to emphasize that our meetings for the next two days present an excellent opportunity for us to engage in meaningful discussions on matters of regional and worldwide importance".
"I remain concerned about China's efforts to build and militarise outposts in the South China Sea".
For a second day Monday, several thousand militant protesters marched in Manila, clashing with riot police who responded with truncheons, water cannons and sonic alarms to keep the demonstration out of sight of the delegates at the ASEAN Summit, which is surrounded by a security cordon.
Local media reporters say 10 people were injured, including six police officers.
Trump also the trip had been "very fruitful" for the United States and pointed to the warm welcomes he had received in capitals like Tokyo, Seoul and Beijing.
About 30,000 North Koreans have defected to South Korea since the end of the 1950-53 Korean War, but majority travel through China. "Despite all the red carpet, Trump's own agenda was largely ignored".
