Travelers arriving at and departing from Singapore during the planned US-North Korea summit should expect flight delays as airspace will be restricted, authorities said in a release on Wednesday. Singapore’s Ministry of Defense has confirmed that airspace restrictions over Singapore will be in place from Jun 10, 8am, to Jun 14, 11.59pm. Singapore’s Minister for Foreign Affairs Vivian Balakrishnan will make an official visit to Pyongyang on Thursday at the invitation of his North Korean counterpart Ri Yong Ho. The decision followed his working visit to Washington on Tuesday when he met US Secretary of State Mike Pompeo. The defense ministers of Japan and South Korea have articulated contrasting positions at a regional security conference on North Korea’s potential denuclearization ahead of the planned summit between U.S. President Donald Trump and North Korean leader Kim Jong-un.
