A former Trump administration official predicted Wednesday that U.S. President Donald Trump could meet with North Korean leader Kim Jong-un for a summit sometime this fall, citing Trump's continued indications of interest in resuming dialogue with the reclusive leader.

Fred Fleitz, a former chief of staff of the National Security Council under the previous Trump administration, made the remarks as speculation persists that Trump and Kim may resume dialogue around the time when Trump visits China for summit talks with Chinese President Xi Jinping, in May.

"I believe there is a good chance of a Trump-Kim summit this fall," said the vice chair of the America First Policy Institute at a press event on the sidelines of a forum hosted by the Asan Institute of Policy Studies.

"President Trump has often indicated that he wanted to resume a successful personal diplomacy ... It is something that Trump believes in that this was a big success that he has to build upon," he said.

Fleitz pointed out that although Trump is open to meeting Kim again, he would not back away from the U.S. demand for denuclearization.
