UPDATE: President Donald Trump said Wednesday that North Korea has not notified the United States about its threats to cancel next month’s summit in Singapore. The president told reporters, as he welcomed Uzbek President Shavkat Mirziyoyev to the White House, he’ll still insist on the denuclearization of the Korean Peninsula when he meets with North Korean leader Kim Jong Un.

North Korea threatened Wednesday to cancel a historic summit with the United States next month amid military exercises conducted by the United States and South Korea. U.S. President Donald Trump and North Korean leader Kim Jong Un are scheduled to meet June 12 in Singapore, and representatives of the two Koreas were set to meet Wednesday to talk about improvements in cross-border relations. Hours before that meeting, though, the North backed out, South Korean Yonhap news agency reported.

South Korea on Monday said it will take down propaganda-broadcasting loudspeakers from its border with North Korea days after the two nations agreed to work toward peace in a historic summit. The South’s Defense Ministry said it will remove dozens of the loudspeakers on Tuesday. The two countries halted the broadcasts ahead of their summit on Friday, which took place in the border village of Panmunjom. The discussions focused on peace talks and on the North Korean nuclear program.

NORTH KOREA: In just one step, Kim Jong Un crossed the southern side of the Korean Peninsula’s Demilitarized Zone for a summit with South Korean President Moon Jae-in, the first time a North Korean leader has stepped into South Korea since 1953.

North Korean leader Kim Jong Un and South Korean President Moon Jae-in met at a historic face-to-face summit Friday with both leaders crossing their borders to shake hands. At the end of the summit, the leaders announced additional plans to reconcile their nations but offered no details on the North’s nuclear weapons program. Kim began the day by stepping into the South to shake hands with Moon as schoolchildren bearing flowers and a military band welcomed him. Kim is the first North Korean leader to cross the demilitarized border since the end of the Korean War in 1953.

A suspected collapse at North Korea’s nuclear testing site likely forced the suspension of further tests and triggered the risk of radiation leaks, Chinese geologists announced Thursday. North Korea’s regime has conducted all six of its nuclear tests on a mountain located in the country’s northeast. Scientists at the University of Science and Technology of China said they collected their data after the most powerful nuclear test on Sept. 3, 2017.

North Korea’s state-run media reported early Saturday that the country is suspending nuclear tests and intercontinental ballistic missile launches ahead of planned summits with South Korea and the United States. North Korean leader Kim Jong Un made the announcement at a meeting of the ruling party’s Central Committee on Friday.
