Plans for a long discussed rail network to link China to six south-east Asian countries are advancing as critical gaps are filled in Cambodia.
An antiquated line to Vietnam built by the French a century ago is at present China's only rail link to the region, but officials began plotting the new network in 1995 to extend the French connection through various national lines all the way to Singapore, the southern tip of mainland south-east Asia.
The network is expected to strengthen economic ties by reducing transport costs and making travel more convenient. A new trade agreement came into effect in January slashing tariffs on most goods exported between China and members of the Association of South East Asian Nations.
