In what could be a significant financial blow to Kim Jong Un’s North Korean regime, China ordered an immediate halt to Chinese tourism to the reclusive state one day prior to President Trump’s arrival as a part of his Indo-Pacific tour.

A number of tourism companies based out of the Chinese city Dandong, which shares a border with North Korea, offer multiple day trips into North Korea, accounting for some eighty percent of North Korea’s $44 million in annual tourism-based revenue.

“It was very unexpected, we had no idea this was going to happen until we received the notification today,” one Chinese tour operator who runs trips to North Korea out of Dandong told Reuters. “This is devastating news for us.”

Although trips to North Korea’s capital city of Pyongyang are no longer permitted, the order does allow for single day trips into North Korea’s directly adjacent city of Sinuiju, which remains a popular tourist destination for Chinese citizens.  North Korean trips out of other, less heavily trafficked Chinese cities, are also still permitted.
