History:
The difficulty of navigating the river has meant that it has divided, rather than united, the people who live near it. The earliest recorded civilisation was the 1st century Indianised-Khmer culture of Funan, in the Mekong Delta. Excavations at Oc Eo, near modern An Giang, have found coins from as far away as the Roman Empire. The first European to encounter the Mekong was the Portuguese Antonio de Faria in 1540 The first systematic exploration began with the French Mekong Expedition led by Ernest Doudard de Lagrée and Francis Garnier, which ascended the river from its mouth to Yunnan between 1866 to 1868. Their chief finding was that the Mekong had too many falls and rapids to ever be useful for navigation. From 1893, the French extended their control of the river into Laos.

Bridges:
There are a total of 4 bridges that are built across part of the Mekong River. The first two is known as first and second Thai–Lao Friendship Bridge. The third bridge is located in Champasak province, in Laos. Unlike the Friendship bridges, this bridge is not a border crossing. Cambodia has one two-lane bridge located near the city of Kompong Cham, on the road linking Phnom Penh with the remote provinces of Ratanakiri and Mondolkiri, and further away Laos.

Myth:
