In Beijing, a auto with a diplomatic license plate of the North Korean Embassy was spotted Monday at the Great Hall of the People, a state building used for activities by the government and the Communist Party of China.
A convoy under heavy security is seen passing into the Diaoyutai State Guesthouse in Beijing where top North Korean leaders have stayed on previous trips to Beijing, China.
Previously, China would not have granted Kim the honor of meeting its president, Xi Jinping. His predecessor also used such a train during his visits.
South Korea's national security adviser, Chung Eui-yong, announced earlier this month that Trump had agreed to meet with Kim to discuss efforts to "achieve permanent denuclearization".

On March 18, the Turkish Armed Forces (TSK) and the Free Syrian Army (FSA) declared full control over the city. It was important to pay attention to the security interests of Turkey, "our ally within NATO", Macron said.

"We are closely monitoring any related movements, using various channels to try to confirm them", the office of South Korea's president, Moon Jae-in, said in a brief statement about news reports about the train.
China is North Korea's only ally, accounting for 90 percent of its trade. It is similar to the kind that Kim's late father, Kim Jong-il, rode when he visited Beijing in 2011.
White House spokesman Raj Shah said the United States could not confirm reports that Kim was visiting China.
Kim Jong-il travelled by private train during his rare visits to China or Russian Federation under tight security.
