During the same period, the U.S. share of global steel production dropped from 12 percent to 5 percent.
Trump noted in a second tweet that North Korea has not conducted a missile test since Nov. 28, and has "promised not to do so through our meetings". Vice President Mike Pence attributes this drastic change in North Korean policy to the isolation techniques employed by the Trump administration.
The US expects North Korea to halt all nuclear and missile testing in advance of any meeting, Pompeo and Treasury Secretary Steve Mnuchin said on Sunday news shows.
He also said that it is not "highly likely" that Trump would go to North Korea for the meeting, but added, "I'm not going to rule anything out". China's drive to share world power has led to conventional, nuclear and space arms races.
On the heels of an intercontinental ballistic missile test from Pyongyang in November, Trump derided Kim as a "sick puppy", drawing cheers from a crowd of supporters at a campaign style rally.
For Trump, one big trap could be the optics.
"They couldn't believe it. But by the following morning the news became FAKE". They failed to produce a deal, but did result in iconic photos of the two leaders smiling together in the final years of the cold war.
"The United States should know and understand our position and should further contribute to the peace and security-building in the Korean Peninsula with (a) sincere position and serious attitude", he wrote in an email to The Washington Post.
North Korea wants to make peace, Trump says
Those officials thought the president would take more time to discuss such a decision with them first.
After months of issuing vague threats, state Assemblyman Ron Kim (D-Flushing) and fellow Korean-American leaders are asking that President Donald Trump tone down his rhetoric and seek peace with North Korean dictator Kim Jung-Un. Talking would not represent a reward or concession, or a signal of U.S. acceptance of a nuclear-armed North Korea. If you go ahead with this, they told Trump, there will be risks and downsides.
Among the subjects said to have been raised was North Korea's willingness to talk about getting rid of its nuclear weapons on the basis that its own safety can be guaranteed. Usually, diplomatic grunts do the tedious pre-talks legwork, exchange proposals, hammer out the fine points, and set the stage for the leaders to come in and close.
In the stands of the Alpensia Biathlon Centre, spectators watching the North's first Winter Paralympians welcomed their presence as a sign of improving ties, and said they hoped the rapprochement would last. Or maybe he'll be unveiling his master plan like James Bond's villains do at the end of the second act?
China helped bring about a dramatic easing of tensions between the United States and North Korea, according state media outlets, adding evidence that the government sees itself as a central player in any agreement despite largely sitting on the sidelines so far.
"OK, OK", Trump said, cutting short the discussion. Cable news reports say Trump didn't even alert his staff about the announcement.
"Part of the reason (Kim) is moving toward diplomacy, I think, is I've heard from North Korea that the extended sanctions have hurt him quite a bit", Richardson said. "And, again, this meeting won't take place without concrete actions that match the promises that have been made by North Korea", she said. "North Korea decides to give up its nukes or has dialogue but simultaneously they continue nuclear weapons". But this isn't John F. Kennedy or Abraham Lincoln - it's #Donald Trump, so don't get your hopes up too high.
