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.
The armed forces and interior ministry have sent hundreds of extra soldiers and police to Gwadar, the southern hub of the so-called China-Pakistan Economic Corridor (CPEC), and more are on their way.
