Actually Hopkirk, the Chinese are the worst drivers I've ever experienced, the rule is that they should drive on the right, but in reality, they drive exactly where they want to, and expect others to get out of their way.
The railway gauge on the Trans Siberian also changes at the Mongolian border, a place called Erenhot, and that causes even more issues with freight.
It is those countries with American influence that drive on the left out there as well, namely Korea, Philippines, Guam, Vietnam - all the rest are on the proper side.
The trick in Paris, Hopkirk, is to drive to the front of your car and don't worry about the sides or rear; it's their duty to stop. Somebody said to buy a 504 and weld I bars on the front and rear bumpers - helps with the parking!
