South Korean leader says he asked China's Xi to act as mediator on North Korea issues

South Korean President Lee Jae Myung says he asked Chinese President Xi Jinping to serve as a mediator to help resolve the North Korean nuclear crisis and ease animosities between the two Koreas. Lee made the remarks while speaking with reporters traveling with him Wednesday on the Shanghai leg of his China trip. He says he made the request during a Monday summit with Xi in Beijing. Lee cites Xi as responding that patience was needed on North Korea issues. China is North Korea’s biggest trading partner and major diplomatic backer.
