HANOI, Vietnam (AP) — The noise is everywhere in Hanoi. As Vietnam pushes for double-digit economic growth, its capital is pursuing an ultramodern vision for the next 100 years. The centerpiece is a $28 billion redevelopment along both banks of the silty Red River that runs through the city. It will cover 11,400 hectares (28,170 acres) — larger than the size of central Paris — and will feature new roads, parks, urban districts and, crucially drainage and other flood controls to contain chronic inundations. But he warned the construction boom also risks diverting capital from the high-tech industries Vietnam wants to develop.
