At the North Atlantic Treaty Organisation summit in July, Trump threatened that the United States would "go its own way" if members did not spend more on defense.
French President Emmanuel Macron, who has a close relationship with Trump, will stress the importance of "collective action" and multilateralism when he addresses the United Nations shortly after Trump on Tuesday.
President Donald Trump will call for global action on the world drug problem, lay out his vision of the US role in the world, and urge a halt to the spread of weapons of mass destruction during next week's gathering of world leaders at the U.N. General Assembly. U.S. Ambassador Nikki Haley said there are no plans to adopt a resolution at Wednesday's meeting.
"The United States is not looking to do regime change in Iran", Haley said on CNN's "State of the Union".
That doesn't necessarily mean Trump will be unwelcome at the United Nations, analysts say - just maneuvered around. Since last year's General Assembly, the withdrawal from the Iran nuclear deal, the cuts in aid to Palestinians and recognition of Jerusalem as Israel's capital, the tariffs on aluminum and steel, and most recently the threats to the International Criminal Court have been fiercely opposed by Europe and Canada. "They have exhausted of Trump's my-way-or-the-highway act and are increasingly hitting the road - or looking to China to fill the vacuum left by the US retreat".
"It's very unlikely to see many people confronting President Trump".
On Friday morning, Trump stirred things up on Twitter by posting: "I will Chair the United Nations Security Council meeting on Iran next week".More news: Tropical depression forms in the Atlantic; three other disturbances tracked

Back in May, Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei decried both the previous and current United States administrations for reneging on their promises and threatening the Islamic Republic, saying that's why Iran does not negotiate and interact with the US.
The U.S. concept note on the meeting circulated to Security Council members does not specifically mention any countries.
Trump's predecessor, Barack Obama, chaired two Security Council meetings, one in 2009 focusing on nuclear disarmament and another in 2014 on "foreign terrorist fighters". It raises the prospect of an encounter, chance or otherwise, between Trump and Rouhani.
Iran and Trump will make for an unpredictable week at the UN General Assembly this week. He will also have meetings with the leaders of South Korea, Egypt, Israel and the United Kingdom.
To that end, Secretary Pompeo has also offered to meet with North Korean Foreign Minister Ri Yong Ho during the week as he prepares to head back to Pyongyang to revive negotiations.
As such world leaders will also be focused on trying to solve several humanitarian crises, from Myanmar to Yemen and Syria to South Sudan.
Haley said Trump will address a high-level event Monday on the "Global Call to Action on the World Drug Problem", which 124 countries have already signed up to support.
