"We speak highly of this visit," Xi said.
The two leaders exchanged views on the situation of the world and the Korean Peninsula.
Xi underscored the China-DPRK friendship, saying, "This is a strategic choice and the only right choice both sides have made based on history and reality, the international and regional structure and the general situation of China-DPRK ties. This should not and will not change because of any single event at a particular time."
According to the report, Kim highlighted that the situation on the Korean Peninsula is commencing to get better.
