President Trump is reportedly considering a visit to the Korean Peninsula's Demilitarized Zone when he tours South Korea next month.

White House officials had visited the area in late September to coordinate logistics for a "special activity" when Trump visits, a South Korean military official told Yonhap News Agency on Tuesday.

"They looked around Panmunjom and Observation Post Ouellette," the source said, referring to areas just north of the inter-Korean border. "His aides are making the relevant preparations."

Trump is scheduled to visit Japan, South Korea, China, Vietnam, and the Philippines next month. The five-country tour comes as his administration faces an escalating conflict with the North Korean regime.

The president tweeted over the weekend that only "one thing would work" to prevent the communist nation from continuing to develop its nuclear and ballistic missile programs.

"Presidents and their administrations have been talking to North Korea for 25 years, agreements made and massive amounts of money paid hasn't worked, agreements violated before the ink was dry, making fools of U.S. negotiators," the president said in a series of tweets on Sunday.

The White House did not respond to a request for comment.
