Despite initial hopes that a new process to modify the rejected plan would start by autumn, most of the rest of 2004 was taken up with discussions over a proposal by the European Union to open up direct trade with the Turkish Cypriots and provide €259,000,000 in funds to help them upgrade their infrastructure. This plan has provoked considerable debate. The Republic of Cyprus has argued that there can be no direct trade via ports and airports in Northern Cyprus as these are unrecognised. Instead, it has offered to allow Turkish Cypriots to use Greek Cypriot facilities, which are internationally recognised. This has been rejected by the Turkish Cypriots. At the same time, attention turned to the question of the start of Turkey's future membership of the European Union. At a European Council held on 17 December 2004, and despite earlier Greek Cypriot threats to impose a veto, Turkey was granted a start date for formal membership talks on condition that it signed a protocol extending the customs union to the new entrants to the EU, including Cyprus. Assuming this is done, formal membership talks would begin on 3 October 2005.
