The White House is softening its stance on North Korea, according to a new report, pulling back its demand that the reclusive nation provides a full, detailed list of its nuclear programs and sites.

NBC News reported Wednesday that President Donald Trump and the American delegation attending the Vietnam summit with North Korean leader Kim Jong Un have changed their tune. The Trump administration is striving to come to an agreement with Kim to make his government abandon its nuclear weapons program.

Trump and Kim met last June, after which Trump said Kim appeared ready and willing to give up his nuclear program. Reports since have suggested North Korea has dismantled some nuclear test sites, but some signs point to other sites still being used.

One such site is the Yongbyon Nuclear Scientific Research Center, located a little more than 60 miles north of the North Korean capital of Pyongyang.

"Yongbyon is the heart of North Korea's nuclear program," nuclear scientist Dr. Siegfried Hecker told NBC.

Thursday morning in Hanoi, Vietnam, Trump said during a roundtable discussion with Kim that he's less focused on getting a deal done quickly and more focused on doing the right deal.

"I've been saying very much from the beginning that speed is not that important to me," Trump said. "I very much appreciate no testing of nuclear rockets, missiles, any of it, very much appreciate it. We just want to do the right deal."
