A North Korean delegation arrived in Beijing yesterday as the two allies step up diplomatic contacts ahead of a landmark meeting between Kim Jong Un and Donald Trump.
Japanese broadcaster NHK said the identity of the visitors was not immediately known. The report comes a week after Kim made his second trip to China in less than two months to again meet with President Xi Jinping. Kim's latest visit was to the northeastern port city of Dalian, as the two countries seek to mend frayed ties.
Relations soured in the past year as Beijing backed a series of United Nations sanctions against its ally. But Beijing wants to avoid being sidelined after Kim's historic summit last month with South Korean President Moon Jae In and ahead of his upcoming meeting with Trump in Singapore on June 12.
