Members of the delegation accompanying Russian President Vladimir Putin during his visit to Pyongyang were expelled from the negotiation room. The fact that the Russian officials entered the hall before the leader of North Korea, Kim Jong-un, angered the protocol service of the DPRK. Foreign Minister Sergey Lavrov, deputy prime ministers, defense and health ministers and the head of Roscosmos were forced to leave the hall after the unexpected situation, which was broadcast live on North Korean state media and Russian channels.

On the night of June 18, Russian President Vladimir Putin paid a state visit to North Korea. He was personally met at the airport by the head of state of the DPRK, Kim Jong-un. The next day, Putin and Kim signed an agreement to deepen cooperation between the two countries. This document provides for mutual assistance in case of aggression against one of the participants.

South Korean Defense Minister Shin Won-sik accused Pyongyang of producing shells for Russia in exchange for food. Since August, Pyongyang has sent Russia about 6,700 containers capable of holding more than 3 million artillery shells, a South Korean minister said.

North Korea's Supreme People's Assembly unanimously approved the cancellation of all economic cooperation agreements with South Korea.

North Korean leader Kim Jong-un has called for South Korea to be designated in the country's Constitution as "enemy number one". He also demanded the demolition of a monument in Pyongyang that symbolizes the reunification of the two countries.

North Korea launched an artillery attack on the territory of Pangyongdo and Eonpyongdo islands. The shells did not reach the territory of South Korea.

North Korean leader Kim Jong-un has ordered the military, ammunition and nuclear weapons industry to accelerate preparations for war against US actions.
