Yunnan patrol officers glide through river duty in slow motion

Uniformed Chinese officers cruise the Mekong River, known as the Lancang River in China, in slow motion in a video filmed in Yunnan Province.

The officers serve in the Yunnan public security department's water patrol team, which has carried out joint river patrols with law enforcement from Laos, Myanmar and Thailand since 2011.

The effort aims to maintain safety along a stretch of the Mekong considered a critical international trade and transport route.
