The Lao People's Army patrol boat was custom-made in China with night-vision capability and two of the most powerful engines on this remote stretch of the Mekong River.

Today, like most days, it sits idle for lack of gasoline, guarded by a single Laotian soldier in flip-flops.

Even occasional patrols by boats like these, supplied by China to the Laotian army and Myanmar police, have successfully subdued the pirates who once robbed the Mekong's cargo ships with impunity.
