The moves are the first practical, if small, steps toward reconciliation and come after an agreement in the joint declaration signed at Friday’s summit between South Korean President Moon Jae-in and the North’s Kim Jong Un.

Activity at several spots along the border indicated North Koreans were taking down the speakers, a defence official said. South Korea started doing the same at 2 p.m. local time, he said.

For decades, with only a few breaks, the two sides have pumped out propaganda from huge banks of speakers as a form of psychological warfare. The South broadcast a mixture of news, Korean pop songs and criticism of the northern regime, while the North blasted the southern government and praised its own socialist system.

As a sign of goodwill, the South had stopped its propaganda ahead of the summit, and the North followed suit.

In another small sign after Friday’s summit, North Korea said Monday it would shift its clocks forward half an hour to align with its southern neighbour starting May 5.

The incremental steps come amid speculation about where Kim will meet U.S. President Donald Trump, who said their planned summit could take place in three or four weeks.
