President Trump spoke Thursday morning about his talks with North Korean leader Kim Jong Un in Hanoi, Vietnam regarding the North Korean nuclear program.

Trump noted that, while "we had a productive time," no deal was signed.

He said that Kim had asked for total removal of sanctions before denuclearization, something to which the US could not agree.

“Basically, they wanted the sanctions lifted in their entirety, but we couldn’t do that ... we had to walk away from it."

"We felt it wasn't a good thing to be signing anything."

"Sometimes you just have to walk, and this was one of those times," Trump said.

“We had papers ready to be signed, it just wasn’t appropriate.”
