Mr. Kim left Vietnam by train on March 2, after a two-day summit with US President Donald Trump and a two-day official visit to Vietnam.

Yonhap quoted sources as saying that Mr. Kim's train passed through Changsha, the capital of Hunan province in central China, at around 9 a.m. on March 3 (local time).

Kim's armored train appeared to return on the same route it had taken, despite speculation that Kim might stop in Guangzhou.

It is not yet clear whether North Korean leader Kim Jong Un will go through Beijing to meet Chinese President Xi Jinping or choose the shortest route to Pyongyang.

If not via Beijing, Mr Kim's train would arrive at Dandong station and then cross the Yalu River on the China-North Korea border on Monday evening or Tuesday morning.

North Korean state media also reported that President Kim Jong Un left Vietnam and returned to Pyongyang, according to Yonhap.

“The chairman expressed satisfaction with the results of the visit and extended sincere thanks to the Party, Government and people of Vietnam for their warm reception,” North Korea’s KCNA news agency reported.

Chairman Kim Jong Un left Dong Dang station carrying “the profound friendship and strong solidarity between the fraternal Vietnamese people and the DPRK people,” KCNA added.

Mr. Kim is the first North Korean leader to officially visit Vietnam in 55 years, since the time of leader Kim Il Sung, Mr. Kim Jong Un's grandfather.
