George keeps insisting (several times over) that China and Taiwan are part of "one China" and that all the countries in the world -- and he goes through them all -- agree about this. I don't know the legal facts of the matter. There is clearly a dispute between China and Taiwan but whether they are still technically "one nation" is something I don't quite understand. Presumably they have separate leaders and governments, so is Taiwan similar to Scotland is to the UK? Part of it with its own separate parliament? Somebody explain it.
