US President Donald Trump yesterday said he wanted a two-state solution to resolve the Israeli-Palestinian conflict, the clearest expression yet of his administration's support for such an outcome.

The Trump administration has in the past said it would support a two-state solution if both sides agreed to it.

Trump, in a meeting with Israeli Prime Minister Benjamin Netanyahu at the United Nations, also said he wanted to unveil a peace plan in the next two to three months.

"I like a two-state solution. That's what I think works best ... That's my feeling," said Trump, who is attending the annual UN gathering of world leaders.

US' Arab allies are strong proponents of a two-state solution.

Doubts have mounted over whether Trump's administration can secure what he has called the "ultimate deal" since December, when the US President recognised Jerusalem as Israel's capital and then moved the US Embassy there.

"It is a dream of mine to get that done prior to the end of my first term," Trump said of an agreement on the conflict.

"I don't want to do it in my second term. We'll do other things in my second term," he said.

Jerusalem is one of the major issues in the Israeli-Palestinian conflict. Both sides claim it as a capital. Trump's move outraged the Palestinians, who have since boycotted Washington's peace efforts, led by Trump's son-in-law and adviser, Jared Kushner.

In reaction to Trump's comments, a senior Palestinian official rejected said Trump's policies were destroying hopes of peace.

"Their words go against their actions and their action is absolutely clear (and) is destroying the possibility of the two-state solution," Husam Zomlot, head of the recently closed Palestinian mission in Washington, told AFP.

On North Korea, Trump heaped praise on North Korean leader Kim Jong but called for strict enforcement of sanctions for now.

Chairing a special session of the UN Security Council on non-proliferation, Trump said to expect "very good news" in the coming months and years from North Korea after his landmark summit with the young strongman in Singapore in June.

"Unfortunately, to ensure this progress continues, we must enforce existing UN Security Council resolutions until denuclearisation occurs," Trump said, reading form a prepared text.

His Secretary of State Mike Pompeo later said that he had a "very positive" talks with North Korean Foreign Minister Ri Yong Ho on the sidelines of the UN General Assembly.

In an unusual claim, Trump accused China of working against his Republican party in upcoming midterm polls, saying Beijing wanted to see him suffer an electoral blow because of his hard line on trade.

"Regrettably we found that China has been attempting to interfere in our upcoming 2018 election coming up in November against my administration," said Trump.

Earlier he opened the UNSC meeting by taking aim at Russia and Iran for backing President Bashar al-Assad's brutal war in Syria.

"The Syrian regime's butchery is enabled by Russia and Iran," Trump told the meeting that he was chairing for the first time.

Meanwhile, Venezuela yesterday accused Trump on of promoting a "military uprising" against socialist President Nicolas Maduro, a day after he said a military coup could topple his unpopular regime.

"All options are on the table, every one, -- strong ones and the less than strong ones -- and you know what I mean by strong," Trump added in yesterday's UNSC meet.

And on Iran, the US president stepped up his attack and accused Tehran of stepping up its "aggression" after signing a nuclear accord in 2015, saying Tehran took advantage of a lifting of sanctions to fund a missile program.

"The regime used new funds from the deal to support terrorism, build nuclear capable missiles and foment chaos," he concluded.
