Between the Green Triangle and Huay Xay 300 km), the Chinese authorities have installed 57aids to navigation, including large beacons on
the shore and on some rocks. In addition, signs indicating the name of villages and sound signals (warning horn) have been installed.
From Bokeo to the Khone Falls, between 1910 and 1930 some 600 concrete beacons were built by the French. Some of them disappeared
but there are still 541 unlighted concrete beacons left in the Lao PDR, although many of them are damaged.
Between Huay Xay and Luang Prabang, in 2014 the MRC installed a GPS Navigation Guided System with a navigation map on some 15 vessels.
The system is fully functional here.
