Macedonia's Parliament on Monday ratified a landmark friendship pact with Balkan neighbour Bulgaria designed to dampen a historic rivalry in a region beset by old ethnic and territorial disputes.<br/><br/>Under the treaty, both countries have renounced territorial claims against each other, and Bulgaria has committed to back Macedonia's bids to join the European Union and NATO.'<br/><br/>The deal also calls for a committee to objectively re- examine common history, which could lead to a review of school textbooks. Bulgaria has already ratified the pact.
