A close aide to North Korean leader Kim Jong Un returned to Pyongyang from Beijing on Saturday, informed sources said, after making a brief trip expected to draw even more speculation after U.S. President Donald Trump abruptly canceled next month's summit with Kim.
Kim Chang Son, a senior official of North Korea's State Affairs Commission, arrived in Beijing on Thursday, the sources said, adding he may have planned to also visit Singapore to prepare for the recently canceled June 12 summit there.
Some sources said another reason the North Korean official may have been sent to Beijing was to arrange a visit to Pyongyang by Chinese President Xi Jinping.
