Pyongyang: North Korean leader Kim Jong-un has received a letter from Chinese President Xi Jinping thanking him for "fruitful" summit talks and warm hospitality, Pyongyang's state media reported Wednesday.

According to Yonhap News Agency, in the letter, Xi stated that the two leaders had exchanged views "in-depth" and reached "important common understanding" on shared concerns. He emphasized that these discussions added "new substance" to the relations between their countries, as reported by the Korean Central News Agency (KCNA).

Xi described the relationship between the two nations as having embarked on "a new historical journey." He expressed his readiness to work collaboratively with Kim to consolidate and develop ties and advance the socialist cause of both countries. Xi had returned to Beijing the previous day after his two-day state visit to Pyongyang, which was his first trip to the North in nearly seven years.

During the summit, Kim and Xi pledged to deepen and expand exchanges across various sectors including politics, economy, culture, and science, as well as to increase high-level contacts between the two sides. However, there was no mention of North Korea's nuclear program or the security situation on the Korean Peninsula from either side.
