One of the most intriguing details that has piqued curiosity since the visit, conducted with great secrecy, is Kim Jong-un's "green train." Kim's famous green train entered Russian territory this morning.
The highly secure green train, often referred to as a "railroad tank" that is said to be impervious to any bullets, has remained a topic of global interest since its departure.
Last week, US media had claimed that Kim would visit Russia to negotiate arms deals. It was suggested that the leaders would discuss a plan in which Moscow would provide satellite and nuclear submarine technology to Pyongyang in exchange for North Korea supplying Russia with artillery shells and anti-tank missiles.
