Mr Warmbier, 21, was sentenced in March 2016 to 15 years hard labour for attempting to steal a propaganda sign from a hotel.
That was used as evidence in his hour-long trial, during which North Korea accused him of committing "hostile acts" against the regime at the urging of a purported member of a church in his home state of OH, a secretive university organization and the Central Intelligence Agency.
Kim Dong Chul, who was born in South Korea but is also believed to have USA citizenship, is serving a sentence of 10 years for espionage in the North, and in April this year, Tony Kim, who also goes by his Korean name Kim Sang-duk, was detained according to the Pyongyang university at which he was working.
The announcement comes as former National Basketball Association player Dennis Rodman is paying a return visit to North Korea. "My objective is to go over there and try to see if I can keep bringing sports to North Korea".
