PHNOM PENH - At a ceremony in August, Cambodia's leader Hun Manet knelt to receive blessings from saffron-robed monks as fireworks and balloons heralded the breaking of ground for a canal he hopes will transform his country's economic fortunes.

Addressing hundreds of people waving the Cambodian flag, Hun Manet said China would contribute 49% to the funding of the Funan Techo Canal that will link the Mekong River to the Gulf of Thailand and reduce Cambodia's shipping reliance on its neighbour Vietnam.
