Workmen install a poster onto a wall surrounding a construction site showing an artist's impression of the new business district of Binhai, located in the Yujiapu financial zone on the outskirts of the city of Tianjin March 2, 2011. Round-the-clock construction is transforming muddy ground into what officials boast will be the world?s largest financial zone, a monument to the ambitions that have driven China to dizzyingly fast growth. When the country?s leaders gather for their annual parliament in Beijing on Saturday, they will endorse plans to tap the brakes on the speeding economy, a shift that is needed to keep inflation and debt, under control for now, from becoming far more troublesome. But they need only make the one-hour trip to the financial district sprouting up in Tianjin to see how hard-driving local officials, cash-rich state-owned banks and the soaring aspirations of people seeking a better life are imperiling their designs for slower, steadier growth.
