Two Chinese citizens have been killed and another wounded in a suspected bomb blast in Laos, Chinese state media say.
China's embassy in Laos confirmed the blast, which occurred on Sunday morning (local time).
The victims had been travelling in a vehicle on the mountain roads of Xaysomboun province, the official Xinhua news agency said.
"Laos military personnel rushed to the scene and the injured, surnamed Zhou, has been shifted to a hospital in the capital, Vientiane, for treatment," Xinhua said.
Chinese embassy officials visited the injured person and demanded a prompt investigation into the "suspected bomb attack," Xinhua reported.
At least one of the Chinese victims was an employee of a mining company from southern China's Yunnan province, it said.
Xinhua did not give further details and it is unclear if the individuals were targeted.
The remote Xaysomboun region has been plagued by sporadic conflict between the government and ethnic Hmong militants for years.
