(ANSAmed) - ROME, AUGUST 28 - A new round of negotiations will take place between Italians and Libyans to try to finalise, at last, after years of unnerving 'stop and go', the historical 'Pact of friendship and cooperation' between Rome and Tripoli. A Libyan delegation is expected this afternoon at Palazzo Chigi, welcomed by Foreign Minister Franco Frattini and the undersecretary to the Prime Minister's office Gianni Letta, to whom Silvio Berlusconi gave the task to conduct the last, extremely delicate stages of the negotiation. The Prime Minister is in fact trying to hurry up the process and if today the 'green light' were to be given, Berlusconi should fly to Libya at the latest by Saturday August 30, to sign the document with Muammar Gaddafi. The 'knot' which is being untied at the moment is the financial coverage which Rome should guarantee to the real big request on which Tripoli has focused the negotiations: the construction by Italy of an expensive coastal motorway which, from Egypt to Tunisia, will cross the whole of Libya on the route of the ancient Via Balbia. An investment of billions of euro (from 3 to 6 billion, according to the preliminary estimates), unsustainable at the moment, which the technicians of the competent Ministries are thinking to spread over several years. A vast demining operation in the African country and other infrastructural interventions complete the package of requests which the Libyans have been presenting for years, to finalise an agreement which was about to be concluded several times, but was never signed because of the new demands continuously presented by Gaddafi. This time, it looks like the right path has been taken. Berlusconi's visit in June gave an impulse to the negotiations and the frequent contacts of the past few weeks between the Prime Minister and the leader of Jamahiriya (the last of which on Sunday) seem to confirm an imminent announcement. Obviously, nothing is taken for granted in the government circles, given the past experiences. ''The negotiation is still open'', diplomatic sources commented, while waiting for more news today. The acceleration given by Berlusconi's government is due to the fact, as sources well informed on the file said, that Libyan energy resources attract the interest of many other ''competitors'' of Italy. Libya, in fact, not only is Italy's major supplier of hydrocarbons (with Eni in the centre of oil relations), but also the point of gathering and departure of thousands of illegal immigrants headed for the Sicilian coasts. On concluding the accord, Rome will gain in return an ending to the economic discrimination of its companies still operative in Libya and bigger participation in the oil sector. Moreover, naturally, the Jamahiriya will have to pay bigger attention to the migratory flows. It is not by chance that the pact signed a year ago between Rome and Tripoli to fight illegal immigration has not been ratified yet and that immigrants continue to sail from the Libyan coasts to Lampedusa.
