There is the Gitzo traveller - use the hook on the bottom to hang you bag - and provide the extra stability.
For the OP:
You can get webbing straps from any camping shop or if you want leather try a cycling shop for Brooks or Carradice saddle bag straps.
You are going to China - it should be easy to find someone willing to sew them on to the underside of your bag.
