Turnbull echoed that line: "I want to say that I do not believe that summit would have occurred had it not been for the absolute solidarity on the very tough economic sanctions on North Korea that have been imposed by the UN security council, that's had the support, obviously, of the United States and Japan and Australia and other countries, but also China". Three, a missile freeze, a nuclear test freeze.
Yet Kimball is anxious by the hard history of negotiations with North Korea, combined with the lack of any timetable or road map for further steps in the latest agreement.
There was even a touch of warmth over the side-by-side stroll by Trump and Kim on the grounds of the hotel used for the summit venue.
"We appreciate President Trump's recent comments about our family", they said.
If implemented, the halting of the joint military exercises would be one of the most controversial moves to come from the summit.
But one stunning step already taken by Trump - the suspension of U.S.
"We would like to seek an understanding of this between Japan, the USA and South Korea", Onodera was quoted as saying. Col. Jennifer Lovett, a spokeswoman, said the command "has received no updated guidance on execution or cessation of training exercises".
There is now confusion in Seoul and Washington DC over whether large joint exercises in August, called Ulchi Freedom Guardian, will go ahead.
"We will continue with our current military posture" until further notice, she said.

A few other conservatives expressed dismay at seeing the USA and North Korean flags side-by-side, and viewed Mr Trump's solicitous manner and warm words for Mr Kim as too much, given his nation's history of human rights violations. Kim is likely to leave this afternoon while Trump will depart tonight.
"Yeah, he's de-nuking, I mean he's de-nuking the whole place".
The video was produced by the US Government to help persuade Mr Kim to make a deal, a White House official said.
It was not immediately clear what specific progress, if any, had been made in preliminary discussions between U.S. and North Korean officials.
Trump also talked about real estate development opportunities in the DPRK. Chris Murphywrote on Twitter.
"North Korea has committed to a complete denuclearisation".
But that language wasn't mentioned in a joint declaration signed by Trump and Kim, and no timetable was set for North Korea to eventually give up nuclear weapons.
Kim appeared alternately bemused and implacable, speaking through an interpreter and flanked by aides including his sister, Kim Yo Jong, as well as foreign affairs minister Ri Yong Ho and Kim Yong Chol, a vice-chairman of the Central Committee of the ruling Workers' Party.
"I think he loved it", the president said.
"We will solve it", Trump replied. "We're going to have a great discussion and will be tremendously successful".
"We shouldn't pretend we haven't seen this movie before".
The president opened his news conference by playing, on a pair of movie theatre-sized screens, a dramatic, slickly produced video with voice-overs in both Korean and English. "South Korea alliances, then this is the way to launch the process", said Evans Revere, a former USA diplomat in South Korea.
"One moment. One choice. It was a awful thing, it was brutal, but a lot of people started to focus on what was going on, including North Korea".
