HANOI, Feb. 26 (Xinhua) -- Top leader of the Democratic People's Republic of Korea Kim Jong Un arrived in Vietnam's northern Lang Son province Tuesday morning by train for his first official visit to the country and the second summit with his U.S. counterpart, Vietnam News Agency reported.

Kim was welcomed at the train station by Vietnamese officials and civilians, reports said. During the visit, the first by a sitting DPRK top leader in 55 years, Kim is expected to meet with Vietnamese leaders.

Kim, who left Pyongyang for Hanoi on Saturday afternoon, will also meet with U.S. President Donald Trump for their second summit on Feb. 27-28 on bilateral relations and issues related to peace on and denuclearization of the Korean Peninsula.

The first DPRK-U.S. summit, held in June 2018 in Singapore, resulted in improved bilateral ties.

Issues such as a roadmap for denuclearization, the lifting of sanctions and whether to issue a war-ending declaration will be the focal points at the upcoming Kim-Trump talks.
