NICOSIA, Nov. 8 (Xinhua)-- Cyprus President Demetris Christofias on Monday strongly warned against any outside pressure during the UN-led negotiating process aimed at solving the long standing dispute in the Mediterranean island, ten days before a scheduled meeting with the UN chief in New York. UN Secretary-General Ban Ki-moon invited Christofias and Turkish Cypriot leader Dervis Eroglu to meet him at the UN headquarters on January 18, in a move aimed at giving impetus to the stalled Cyprus negotiations. 'It is out of the question that I will be at the receiving end of any pressure at the New York meeting,' Christofias told reporters after another negotiating session with Eroglu. 'I have been given assurances that no change will be brought about in the Cypriot-owned process and there will not be arbitration or any other modification of the UN role,' he added. Christofias, a Greek Cypriot, has been engaged in re- unification negotiations with Turkish Cypriot community under UN auspices for over two years, but they have stalled on the thorny issue of properties. Turkey sent troops to northern Cyprus in 1974, in response to a coup by Greek army officers, forcing almost 200,000 Greek Cypriots to abandon their properties, which were distributed to relocated Turkish Cypriots and mainland Turkey settlers. Christofias said that he and Eroglu had a further discussion on the preparation of their meeting with Ban Ki-moon. UN Secretary-General's special advisor on Cyprus, Alexander Downer, said the UN meeting will be very important for the negotiations. 'I hope that it will give momentum to the process of the negotiations,'Downer said. He assured that the United Nations will not try to arbitrate or impose anything on the two leaders. 'We have to bear in mind that even if the two leaders reached a solution, this has to be approved separately by the two communities,' Downer said. 'We do not want a repetition of what happened in 2004,' he added in reference to a UN proposed solution which was approved by Turkish Cypriots but was rejected by Greek Cypriots, who argued that the blueprint was grossly one-sided.
