DPRK state media, notably emphasized the importance of the visit, stating it was the first since Kim and Xi had "agreed on strengthening the cultural exchange".
It did not elaborate on its itinerary, but China's Xinhua News Agency said that the group will leave for the North on Friday at the invitation of the ruling Worker's Party of Korea. Instead, the session focused on North Korea's budget and changes in leadership personnel.
It also urged Kim to participate in the exchange of information with global organisations and to allow meetings between separated Korean families.
Chinese foreign minister Wang Yi held bilateral talks with his North Korean counterpart Ri Yong Ho on April 3. This year's event will be held from Wednesday to next Tuesday.
Seoul, Baik added, "will watch with interest whether it will lead to a performance in China by North Korean artists that was cancelled in December 2015".
Beijing is North Korea's sole major ally, an alliance dating back to the 1950-1953 Korean War, but relations deteriorated after China backed United Nations sanctions to punish Pyongyang over its nuclear weapons programme. It was his first overseas trip since he took office in late 2011.
Kim's visit was seen as meant to secure more bargaining chips ahead of his planned meetings with President Moon Jae-in and U.S. President Donald Trump.
"Meetings are being set up right now between myself and Kim Jong Un", Trump told reporters as quoted by a White House press pool report.
One North Korean expert said the visit was a sign that China's diplomacy on Pyongyang is "getting more active" and suggests it is now rooted in two primary goals.
