A truck leaves a ferryboat in front of the newly built bridge over Danube that links Calafat in Romania to Vidin in Bulgaria, 320 km southwest of Bucharest, October 24, 2012. Romania's infrastructure is the least developed in the European Union after years of repeated delays and is one of the main complaints of foreign investors, who say decrepit transport cancels out an advantageous location at a trading crossroads and relatively low labour costs. The Calafat-Vidin bridge should be open in six months. REUTERS/Bogdan Cristel (ROMANIA - Tags: TRANSPORT SOCIETY)

A ferryboat moves along the Bosphorus and past the city's skyscrapers (rear) in Istanbul in this September 3, 2012 file photo. The developer of a five-tower luxury compound perched on the edge of the new financial district on Istanbul's Asian side is putting the finishing touches to a complex that will boast eco-friendly apartment blocks, swimming pools and lush green parks. It is the sort of development that overseas property buyers in Turkey, mainly from Europe, have usually shied away from, investing instead in holiday homes along the country's Mediterranean and Aegean shores. But a new wave of wealthy investors from the Middle East and Russia is increasingly eyeing luxury developments in bustling Istanbul, lured by a relaxation in property laws, relatively cheap prices and a thriving economy.
