I'm afraid the EBU was so clear about Kosovo, but not so clear about China. They said Kosovo CAN'T enter but about China they tweeted: "NO PLANS for China to take part RIGHT NOW".
This means we can't rule this out, unfortunately.
And more worrying, look at this:
Wow, the EBU is more hypocritical, evil and dirty that I thought they would be.... :?
1- They clearly admit that they care more about their members than their audience. That's nice, EBU. That's really nice....
2- EBU seems to ignore their own rules. They keep on the silly thing of "bringing nations together" bla bla bla... And they even say the contest doesn't have geographical limits... WTF.
3- Decisions to be taken by the Reference Group. So our only hope is that 6 of the participant countries have common sense and are not corrupt. Too much to ask for I'm afraid
