GWADAR, Pakistan (Reuters) - A heavy police presence, guarded convoys, new checkpoints and troop reinforcements have turned parts of the southern port city of Gwadar into a fortress, as Pakistan's powerful military seeks to protect billions of dollars of Chinese investment.

Securing the planned $46 billion economic corridor of roads, railways and pipelines from northwest China to Pakistan's Arabian Sea coast is a huge challenge in a country where Islamist militants and separatist gunmen are a constant menace.
