Asked about Trump's potential options at the negotiating table in future talks with North Korea, more Americans say they'd oppose than favour withdrawing USA troops from South Korea (41 per cent to 29 per cent) and giving economic aid to North Korea (47 per cent to 24 per cent) in exchange for Kim surrendering his country's nuclear weapons. They're blowing it up. In fact, it was actually 4 of their big test sites.
"And the big thing is it will be a total denuclearization, which has already started taking place".
The announcement was widely anticipated following President Donald Trump's meeting with North Korean leader Kim Jong Un last week.
"Obviously, we are at the very front end of the process, the detailed negotiations have not begun", Mattis told reporters on Wednesday.
"I wouldn't expect that at this point", he added.
Mattis was sat next to Trump at Thursday's Cabinet meeting.
The site in question is the Sohae Satellite Launching Ground where North Korea has previously tested "liquid-propellant engines for its long-range ballistic missiles", according to a USA official who spoke to Reuters. Trump said he developed a "special bond" with Kim and upon his return to the United States tweeted that "there is no longer a Nuclear Threat from North Korea".
CNN reported Tuesday that the remains of as many as 200 US troops could be returned as part of that agreement, but officials said it was too early to say how many would be included.
The South Korean president also said that during the visit his country and Russian Federation were planning to sign agreements on the comprehensive development of economic cooperation.More news: Yoga Day 2018 celebrated all over the world

North Korea has spent considerable effort and resources to develop the site as a "civilian space programme" facility, denying that it has a military application, said Jenny Town, a research analyst at the 38 North.
"Maybe in the future but right now our military is focused on assets and security in the peninsula because our security in the peninsula is still very vulnerable and we are focusing on our region", she said.
Although Trump has hailed the Singapore summit as a success, sceptics have questioned whether he achieved anything, given that Pyongyang, which has rejected unilateral nuclear disarmament, appeared to make no new tangible commitments in a joint written declaration.
Trump repeated his thanks to Chinese President Xi Jinping for supporting sanctions, although he said that the border between China and North Korea was "getting a little weaker now".
A majority of Americans now approve of President Donald Trump's handling of US relations with North Korea, a change that comes after his historic summit with that country's leader, Kim Jong Un.
"That's OK. That's OK".
"We need to closely watch North Korea's steps toward denuclearisation".
Trump's critics have responded to his confidence in the agreement struck with Kim at the summit with reminders that North Korea has never signed such a deal that it didn't later break.
Another element of the Singapore joint statement was a North Korean promise to hand over remains of U.S. soldiers, marines and airmen still unaccounted for since the 1950-53 Korean war.
