On last year's Day of the Sun, Kim put on a military parade bristling with his latest ballistic missiles, exacerbating worldwide tension over his nuclear weapon and missile programmes. With that in mind, the South has already started to renovate the Peace House at Panmunjom to greet North Korean delegates ahead of the inter-Korean summit, leading up to the meeting between the two leaders.
Moon is set to meet the reclusive North Korean leader next Friday for what would be a third inter-Korean summit.
Kim and Ri Sol Ju watched the troupe perform choreodrama "Red Women Company" at the East Pyongyang Grand Theatre on Monday, the Korean Central News Agency said.
Kim plans to hold a summit with South Korean President Moon Jae-in on April 27 and with US President Donald Trump in May or in early June. It also wants to strengthen ties with the United States ahead of the country's planned meeting with the North.
Kim reportedly invited Xi to North Korea during his visit to China in late March.
"We expect the summit will confirm the denuclearisation will (of North Korea)".
North Korean leader Kim Jong-un asked for China's economic assistance, as well as backing for the regime's survival and the easing of military threats, Asahi Shimbun reported Tuesday. "The United States will insist on complete, irreversible and verifiable North Korea's abandonment of its nuclear program in rigid timeframe".
A South Korean government minister said on Tuesday that the goal of the forthcoming inter-Korean summit should be to sign a peace treaty, amid high expectations for the first meeting between the leaders of the divided countries in a decade.
Kim, in a meeting with Song on Sunday, said he was personally meeting the visiting performers out of respect for Chinese President Xi Jinping and said he wanted to launch a "fresh phase of development" of relations between their countries. North Korea might have wanted to increase its leverage ahead of the historic summits, and China might have meant to show that it is still a major player in resolving the North's nuclear standoff.
South and North Korea are discussing plans to announce an official end to the military conflict between the two countries that are still technically at war, the Munhwa Ilbo newspaper reported, citing an unidentified South Korean official.
