In his speech marking the Commemoration of the Korean War Armistice Day, Thursday (28/7), Kim Jong Un said North Korea was ready to deploy its nuclear weapons and go to war with the US if necessary. Kim Jong Un even threatened to destroy South Korea if they did not stop their provocations, such as doing military exercises with the US. Apart from North Korea's nuclear test, Jokowi and Yoon discussed a number of things. Starting from cooperation in the economic sector, investment, the development of the Capita City of Nusantara (IKN) project, the KF-21 fighter jet, to regional and global issues. Yoon also appreciated Indonesia's presidency at this year's G20 forum and said he couldn't wait to attend the summit which will take place in Bali next October.
