Abe doesn't want Trump to strike a compromise that would leave Japan exposed to shorter-range missiles that do not threaten the US mainland or that relieves pressure on North Korea before it takes concrete steps toward complete denuclearization.
In other words, he would not seek a complete denuclearisation deal with Kim Jong Un in Singapore, only laying the basis for further talks - between the two leaders and between their aides. This is set to be an historic meeting, the first of its kind.
After weeks of uncertainty, President Trump called off the summit last week, blaming "open hostility" from North Korea.
U.S. State Department spokeswoman Heather Nauert has denied the U.S. would pay for North Korea in Singapore and said Washington wasn't asking anyone else to, either.
With days to go before the meeting, it remains unclear whether Pyongyang is willing to take that step, or whether it is using the promise of talks as a way of easing Trump's "maximum pressure" campaign. The CIA's Kim has usually joined him.
But Senator Payne said it was clear the meeting would be part of a process, and not a one-off.
One, on customs and protocol, primarily is assembled by the State Department and shared with much of the USA delegation.
Sanders told reporters on Monday in Washington that the summit would start on the morning of June 12.
U.S. officials believe Kim is extremely anxious about security at the summit and is fearful of assassination attempts, according to two people familiar with the matter.
Trump and Kim will meet at a luxury resort on Sentosa Island in Singapore, according to the White House. He confirmed that he and Kim Yong-chol did, indeed, discuss that possibility.
It comes after a Washington Post report cited two USA officials suggesting the Trump administration has been "seeking a discreet way" to help pay Mr Kim's hotel bill. Trump, who had previously canceled the summit, abruptly announced the meeting was back on, the Guardian reported.
After meeting Kim Yong Chol, Trump said that the United States was "not going to spend" and that neighbouring countries - South Korea, Japan and China - should be ready to shoulder the costs. White House officials declined to describe either present.
