Korean Demilitarized Zone

Attention is turning to whether Donald Trump could hold another summit with North Korean leader Kim Jong Un, revisiting the diplomacy of Trump's first term, which produced meetings in Singapore, Hanoi and the Demilitarized Zone but no binding agreement on denuclearisation. With Trump back in the spotlight, observers are debating whether renewed US-North Korea engagement is realistic and what concessions either side might demand this time.

The South Korean military and the United Nations Command have opened an investigation into an explosion in the Demilitarized Zone separating North and South Korea. The joint probe aims to determine the cause of the blast in one of the world's most heavily fortified border areas, where any incident carries heightened security and diplomatic sensitivity.
