HANOI, Vietnam (AP) — Tourists, hawkers and motorcyclists rub shoulders every morning in the congested alleyways of Hanoi’s low-rise Old Quarter, which seems generations away from the office towers and electronics megastores springing up in other parts of the capital. The quarter’s street grid, laid out in the 15th century, is still dominated by dilapidated shops selling everything from brass gongs to bamboo scaffolding.

It is now among Asia’s best-preserved urban hubs of traditional commerce — thanks largely to decades of inattention. The 82-hectare (203-acre) downtown area is crammed with Buddhist temples, pagodas and French colonial shophouses, whose original tiles and peeling yellow paint have become a draw for foreign visitors.
