South Korea has dismantled huge loudspeakers used to blare anti-Pyongyang broadcasts and K-pop songs from its border with North Korea.
The move came as the South’s president asked the United Nations to observe the North’s planned closing of its nuclear testing site.
The dismantling of dozens of South Korean loudspeakers was in line with reconciliation steps the leaders of the rival Koreas set at their historic summit last Friday.
It was still unclear if such measures could bring permanent peace because no major breakthrough in the North Korean nuclear standoff was produced after the Korean summit.
South Korean soldiers disassembled loudspeakers at multiple front-line areas before pulling them away from the border, according to Seoul’s defence ministry.
Before the summit both Koreas had halted propaganda broadcasts along the 248-kilometre (154-mile) long border.
Cold War-era propaganda warfare had resurfaced in 2016 when tensions rose sharply after the North’s fourth nuclear test.
Seoul broadcast criticism of the North’s abysmal human rights conditions, world news and weather forecasts as well as pop songs.
The North broadcast anti-South messages and praise for its own political system.
Some experts say Mr Kim’s sincerity would be tested during his planned meeting with President Donald Trump in what would be the first-ever North Korea-US summit talks since the end of their fighting in the 1950-53 Korean War.
Mr Trump said on Monday he likes the idea of going to the southern side of Panmunjom, the place for the Korean summit, to meet Mr Kim, though he said Singapore was also under consideration.
He said on Saturday that his meeting with Mr Kim could happen in the next three to four weeks.
During Friday’s summit, Mr Kim told South Korean President Moon Jae-in that he would shut down his country’s only known nuclear testing site in May and allow outside experts and journalists to watch the process.
Mr Kim also said he would be willing to give up his nuclear programmes if the United States commits to a formal end to the Korean War and a pledge not to attack the North, according to South Korea’s presidential office.
Mr Kim denied such views, saying the site has two underground tunnels to be used for new tests.
During a telephone call with UN secretary-general Antonio Guterres on Tuesday, Mr Moon said he wants the UN to observe the work to close down the Punggy-ri site.
Mr Moon also asked for the UN to formally declare its support for his recent summit declaration with Mr Kim, and Mr Guterres responded that he would try to contribute to an establishment of peace on the Korean Peninsula, according to Mr Moon’s office.
According to their summit accord, Mr Kim and Mr Moon agreed to achieve “a nuclear-free Korean Peninsula through complete denuclearisation”, rather than clearly stating “a nuclear-free North Korea”.
North Korea has long said the term “denuclearisation of the Korean Peninsula” must include the United States pulling its 28,500 troops out of South Korea and removing its so-called “nuclear umbrella” security commitment to South Korea and Japan.
Mr Kim could offer more disarmament concessions during his meeting with Mr Trump, and some analysts say Mr Kim may announce scrapping North Korea’s long-range missile programme, which has posed a direct threat to the United States.
