Tens of thousands of Chinese tourists are believed to visit North Korea every year, with many crossing through the Chinese border city of Dandong

BEIJING: Chinese tourists have been involved in a major bus accident in North Korea that caused a large number of casualties, China’s state media and the government said on Monday, without giving a precise break-up.

Chinese visitors account for about 80 percent of all foreign tourists to North Korea, says a South Korean think-tank, the Korea Maritime Institute, which estimates that tourism generates about $44 million each year in revenue for the isolated country.

Chinese diplomats have rushed to the scene of Sunday’s accident in North Hwanghae province, the foreign ministry said.
