BEIJING/SEOUL -- North Korean leader Kim Jong Un is visiting China for the fourth time in a year as he seeks the bigger neighbor's support in setting another summit with the U.S., a development seen as giving Beijing a bargaining chip for trade talks with Washington.
Kim insists on gradual denuclearization and demands that the U.S. ease sanctions on his country before that process is complete. He likely aims for the White House to accept those terms through the backing of Chinese President Xi Jinping.
