That is why both sides (GC and Turkey) are playing to time.
Turkey wants to find a solution to Cyprus before October 3, but that is exactly the reason T-Pap is not sitting on the table.
GC strategy is that. let's get the Turkey to sign this document first. Then the next round is to ask to start political relations with Turkey like opening embassies, etc. etc. The idea is that Turkey will cave in to any demand in order to be a part of EU, so we can get whatever we want before Turkey becomes a member.
The other side of the coin is this. Turkey will sign the protocol with GC administration. And negotiations will start on October 3rd. But Turkey also will not want to solve the Cyprus problem before they are in the EU for sure. GCs can not guarantee that Turkey will ever get into EU and Turkey knows this. France for example is even changing its constitution this week to make it compulsory for the French Government to go to referendum for any new applicant country. Seeing this Turkey will never completely solve the Cyprus problem before she is securely inside the EU. What if Cyprus problem is solved the way GCs want it but at the last minute Turkish EU entry is refused by any member including GCs. That is a risk no Turkish PM will take.
SO as I have said in this forum. Prepare yourself for a long ride. Because Cyprus Problem can only be solved simultaneously at the Turkeys' EU entry. That mean we are here in this forum talking at least another 10 to 15 years. In 10 to 15 years "kim olur kim galir"....
Good luck to all of us,
