There are two Koreas in the world today they are the South Korea and the North Korea but we have not heard of one Korea policy at all although they are looking for a unified nation. Furthermore, before the East/West German merged as one today there was not one German policy neither the North/South Vietnam. Why is there a one China policy that bothered Taiwan people to face it? Isn’t it funny and weird there is none claiming one USA, one Japan, one France or one Russia why China keeps asking for one China? Obviously, there is more than one that’s why they are hunger for the only one.
