Chinese President Xi Jinping on Wednesday met a visiting delegation from North Korea's ruling party, China's Xinhua state news agency said, without providing other details.
Senior North Korean diplomat Ri Su Yong is visiting China.
Ri was the country's foreign minister until he was named a member of the politburo during a recent congress of North Korea's ruling Workers' Party.
On Tuesday, Ri met the head of the international department of China's Communist Party.
China is reclusive North Korea's only major ally but has been angered by Pyongyang's nuclear and missile tests and signed up to harsh new U.N. sanctions against it in March.
But China has been reluctant to take tougher action, such as completely shutting the border the two countries share, for fear that North Korea could collapse in chaos.
