A senior South Korean official said Thursday that he anticipates "some new progress in a few days" regarding North Korea-related issues, but he noted it is not about the resumption of dialogue between Washington and Pyongyang.

The official made the remarks during a meeting with reporters in Washington amid speculation that U.S. President Donald Trump could seek a meeting with North Korean leader Kim Jong-un when he visits China in April.

"There may be some new progress in a few days. It is not anything significant, but it is intended as a gesture of goodwill that can serve as a starting point (for progress in diplomacy with North Korea)," the official said.

"It doesn't go as far as dialogue between the U.S. and North Korea," he added.

He also pointed out North Korea's lack of interest in diplomacy with Seoul or Washington.
