美国有线新闻 CNN 各国首脑将出席联合国大会 特朗普首秀引关注（在线收听）

Starting things for us this September 18th, the United Nations General Assembly. It's a branch of the U.N. and it's the big one. All 193 members of the United Nations are part of the general assembly, and they're having their general debate starting this Tuesday.

These events are held annually and have a theme. This year is focusing on people, striving for peace and a decent life for all on a sustainable planet.

But many other subjects will certainly c?o??me up. The U.S. expects those to include North Korea's weapons programs. The country test-fired another missile over Japan late last week. The international nuclear deal with Iran could also factor in, as well as the civil war in Syria and terrorism around the world, like the bombing attack on a subway in London that injured 30 people on Friday.

International leaders will be listening to what U.S. President Donald Trump has to say about some or all of these issues when he speaks on Tuesday.

The speech will also be closely watched in part because the U.S. contributes the largest share of the United Nations budget, about 22 percent of it. And President Trump has called for America's contribution to be reduced.

RICHARD ROTH, CNN SENIOR UNITED NATIONS CORRESPONDENT: The flags are up. It's time for another United Nations General Assembly global get-together. As always, the United States is the host country.

Much of the world's big names will attend, none bigger than President Trump himself, whose name has been just up the street from the U.N. for years, at the Trump World Tower building.

Trump, a New York real estate mogul, has not always embraced the U.N. After his election, Trump said the U.N. was a club where people like to talk.

DONALD TRUMP, PRESIDENT OF THE UNITED STATES: Welcome to the White House.

ROTH: Trump was more conciliatory when members of the U.N. Security Council visited the White House in April.

TRUMP: I have long felt the United Nations is an underperformer, but has tremendous potential.

ROTH: President Trump will speak to the entire world for the first time from here and the General Assembly rostrum, the leader who vowed fire and fury if Kim Jong-un threatens the U.S., will be closer to North Koreans than he ever has been in his life.

The North Korean delegation will be seated here in the front row, just 20 feet away from where President Trump speaks to the General Assembly.

NIKKI HALEY, U.S. AMBASSADOR TO THE UNITED NATIONS: I think you're going to have the president who did the bombing on Syria from the chemical weapons, the one that has gone against ISIS in both Syria and Iraq at record pace.

ROTH: Other first time speakers include President Emmanuel Macron of France. It is also the first U.N. General Assembly for Secretary General Antonio Gutierrez.
