A North Korean delegation led by Deputy Foreign Minister Ri Kil-Song has left for China, the Korean Central News Agency said Thursday.

The delegation left after the second summit between U.S. President Donald Trump and North Korean leader Kim Jong Un, held in Hanoi February 27-28, ended without an agreement.

They arrived in Vietnam on Tuesday morning, after taking a train journey of more than 60 hours from Pyongyang.

Their leader Kim Jong-un is scheduled to stay in Hanoi for an official visit on Friday and Saturday.
