BEIJING China's embassy in Laos has issued a safety warning to its citizens there after a Chinese national was shot dead in the country's Xaysomboun province.
Chinese workers have increasingly come under attack as companies expand abroad as part of President Xi Jinping's Belt and Road plan to build infrastructure with the rest of Asia and beyond, often in politically unstable places.
One Chinese national was killed on Friday by an unidentified gunman, the embassy said in a statement posted to its website late on Sunday.
Two Chinese people, including an employee of a mining company, were killed in a suspected bomb blast on a vehicle in the region in January 2016.
Beijing sees its neighbour as an important route to Southeast Asian ports for landlocked parts of southwestern China such as Yunnan.
