Trump, Kim sign 'comprehensive document' after historic summit

Donald Trump and Kim Jong-un signed a 'very comprehensive' document after their historic summit on Tuesday, with the U.S president saying that the process of denuclearisation on the Korean peninsula will begin 'very soon' and the North Korean leader promising to leave the past behind.

The two leaders had a one-on-one meeting, with translators only, followed by an expanded meeting including their top aides and a working lunch at Capella Singapore hotel in Sentosa Island after months of diplomatic twists and turns.

"We're signing a very comprehensive document, and we've had a really great time together, a great relationship", Trump said while signing the document along with Kim in the presence of media at the end of the summit - the first between a sitting U.S president and North Korea's top leader.

It was unclear what the document was about but Trump said the public will find out soon.

In response to a question about denuclearisation, Trump said, "We're starting that process... very quickly."

"We have decided to leave the past behind," Kim said through a translator, at the signing table.

"The world will see a major change," he added.

Trump said he was very proud of what took place and the two leaders would "take care of a very dangerous problem for the world."

The 71-year-old Trump said the summit worked out far better than expected and he's developed a "very special bond" with 34-year-old Kim.

"We'll meet again, we'll meet many times," said Trump when asked whether the two leaders will meet again.

He said Kim is "a very talented man" who "loves his country very much".

Trump said he "absolutely" will invite Kim to the White House.
