Secretary of State Mike Pompeo said on "Fox News Sunday", "Our eyes are wide open with respect to the risks, but it is our fervent hope that Chairman Kim wants to make a strategic change".
The Yomiuri ShimbunThe government has requested that U.S. President Donald Trump visit Japan immediately after his meeting with North Korean leader Kim Jong Un in Singapore on June 12 and hold talks with Prime Minister Shinzo Abe, according to sources familiar with Japan-U.S. relations.
Pompeo added that the U.S. "will have to provide security assurances" to Kim as well.
North and South Korea affirmed their commitment to the goal of denuclearisation of the peninsula at a summit last month, and Pyongyang announced at the weekend it will destroy its only known nuclear test site next week. But he said the United States would not be willing to invest taxpayer dollars to help the DPRK.
"If we get denuclearization, of course, there will be sanctions relief, certainly".

Roh Jae-cheon, spokesman for South Korea's Joint Chiefs of Staff, said the South's military has seen signs that the North is conducting "preparatory work" so that it can carry out its plans to shut down its northeastern testing ground. Thae predicts it would then eventually seek joint economic projects with South Korea, such as the Kaesong Industrial Complex that used to employ North Korean civilians and provided a revenue stream for the regime.
The news of another China-North Korea powwow came just as Japanese media reported that North Korea expressed a lack of trust in the United States when Kim visited Beijing for a meeting with Chinese leader Xi Jinping on May 7 and 8.
North Korea is moving ahead with plans to close its nuclear test site next week, South Korea's military said Tuesday, an assessment backed by USA researchers who say satellite images show the North has begun dismantling facilities at the site.
However, on May 13, USA national security advisor John Bolton made the US stance clear when he said no benefits would flow to the North Korean regime unless a denuclearization process was "completely underway that's irreversible".
"We will need to watch carefully and examine what Trump and Kim do in the coming weeks to have a better idea of what the summit outcome will be", she said.
