A train crosses the Royal Border Bridge, as fishermen are seen catching salmon in the harbour mouth at Berwick Upon Tweed in Northumberland August 22, 2013. The Royal Border Bridge opened in the mid 19th century, completing a rail link from London to Edinburgh. It is located in Berwick Upon Tweed, England's northernmost town, which has passed between English and Scottish control over a dozen times. Signs of ancient conflict - from centuries-old fortifications to historic battlefields - score the landscape around the English-Scottish border. But many living in the region lead lives straddling both sides, and express practical concerns about the possibility of a more formal split between the two nations in the event of a yes vote in next year's referendum on Scottish independence, which will be held on September 18, 2014.

A worker welds girders at the 168 Platinum mall construction site in Udon Thani in northeastern Thailand April 9, 2013. The malls, factories and construction sites in Thailand's northeast are emerging alongside its farms as a potent economic fuel in one of Asia's top emerging markets. Growth in Thailand, Southeast Asia's second-biggest economy, has begun to slow, but the economy of the northeast is in the grip of a boom. Work on the 800,000 square metre site began in January 2013 and the mall is scheduled for completion in November. Picture taken April 9, 2013.

The Bosphorus bridge (R) and Istanbul's Levent financial district (rear), which comprises of the headquarters of leading Turkish companies and popular shopping malls, are seen from the city's Asian side in Istanbul May 28, 2013. Unlike the oil-fuelled economies of the Gulf, whose Islamic debt issuance is primarily sovereign, Turkey has a powerful private sector which is increasingly eager to finance international projects using sharia-compliant products. As part of plans to celebrate the 100th anniversary of the founding of the modern republic in 2023, Turkey aims to turn its economic and cultural capital Istanbul into a major financial centre. It foresees $350 billion of infrastructure spending on the project, with Islamic finance expected to be one of the major sources. Picture taken May 28, 2013.

A construction worker stands atop a steel girder as he attaches a crane to it at a building site for new apartment blocks located on the outskirts of Beijing September 24, 2009. Chinese housing prices, which have surged since March, will soon lose their upward momentum and even start to fall around the end of this year, boding well for a more sustained contribution to overall economic growth and providing a valuable prop for an economy adjusting to a slump in exports, analysts say.

A construction worker sits with his bottle of tea atop a girder on a building site in central Beijing August 5, 2009. China is executing a $586 billion stimulus package, announced last November which includes massive construction projects, to help the world's third-largest economy overcome the global economic slump. But experts warn that China's economic recovery was not yet on a solid footing, so an early end to the stimulus now coming from tax cuts and massive fiscal spending could lead to a new downturn.
