Wrapping up his extensive tour of Asia, President Donald Trump on Tuesday 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.

Trump told reporters in Manila that the "fruits of our labour are going to be incredible." He was closing a nearly two-week trip through Japan, South Korea, China, Vietnam and the Philippines that included one-on-one meetings with the leaders of those nations during which he stressed trade.

The president, who campaigned on shredding multilateral trade agreements he has deemed unfair, insisted during his travels that multibillion-dollar deficits that favour U.S. trading partners will be reduced to zero, and that trade overall must be fair and mutually beneficial.

"The United States has to be treated fairly and in a reciprocal fashion," Trump tweeted before heading back to Washington, where he is scheduled to arrive later Tuesday. "The massive TRADE deficits must go down quickly!"

Trump told reporters before departing an international summit, "We've had a tremendously successful trip. Tremendous amounts of work was done on trade."

The president spoke along the sidelines of the annual East Asia Summit of leaders from throughout the Asia-Pacific region, his final summit after attending a gathering of the Association of Southeast Asian Nations on Monday. Trump said he planned to make a "major statement" about his trip from the White House later this week, and spoke of the "many good friends" he made during the trip.

In Manila for the Association of Southeast Asian Nations conference, and the subsequent East Asia Summit, Trump looked to strengthen ties with Pacific Rim allies, aiming to strike one-on-one trade deals rather than multinational trade agreements, and increase pressure on North Korea to abandon its nuclear program.

He met with Indian Prime Minister Narendra Modi and highlighted their two nations' "deeper and more comprehensive" ties, looking to strengthen a relationship that is vital to the U.S. vision of an Indo-Pacific region that attempts to de-emphasize China's influence.

He jointly met with Australian Prime Minister Malcolm Turnbull, with whom he had a contentious phone call last winter, and Japanese Prime Minister Shinzo Abe, who hosted the president in Tokyo earlier in the trip. 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.
