- China has invested $46 billion into the China-Pakistan Economic Corridor
- Hundreds of security personnel deployed in Gwadar to protect CPEC
- Militancy, insurgency, big threats to security of 2442 km long corridor
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.
"Soon we'll start hiring 700-800 police to be part of a separate security unit dedicated to Chinese security, and at a later stage a new security division would be formed," Jafer Khan, regional police officer in Gwadar told Reuters.
A senior security official in the town of around 100,000 people said a further 400-500 soldiers had been recruited as a temporary measure to protect Chinese nationals.
On a recent visit, an SUV carrying Chinese visitors was escorted by two police cars and an army vehicle, while police blocked traffic at every crossroad along the route. It was not clear who the passengers were.
Keeping foreign workers and executives safe in Gwadar, which has expanded significantly over the last 15 years largely thanks to Chinese investment, is relatively straightforward.
The same cannot be said of the corridor as a whole.
Its western branch passes north through Baluchistan province, where ethnic Baluch separatist rebels are opposed to the CPEC project and chafing under a military crackdown.
It skirts the tribal belt along the Afghan-Pakistan border where Islamist militant groups including the Pakistan Taliban and al Qaeda have long been based, and takes in Peshawar, scene of some of the worst insurgent atrocities of recent years.
Pakistan's Planning Ministry does not yet have specific estimates on how many jobs the CPEC will create in Pakistan, although officials believe the project could generate hundreds of billions of dollars for the economy over the long term.
Enhanced security goes beyond Gwadar and across Baluchistan, an arid, sparsely populated province bordering Iran and Afghanistan which sits on substantial deposits of untapped natural gas.
"We have tightened our security in those areas where the corridor is supposed to pass. We cannot allow Pakistan's economic backbone to be held hostage," Sarfaraz Ahmed Bugti, the provincial home minister, told Reuters.
The tough approach means anger is growing among separatist rebels and the broader Baluch community.
"We consider the China-Pakistan Economic Corridor as ... an occupation of Baluch territory," said rebel spokesman Miran Baluch, a member of the Baluchistan Liberation Front (BLF), adding its fighters would attack anyone working on the project.
Militant, insurgent and sectarian groups carried out 625 attacks across Pakistan in 2015, down 48 percent from 2014, said an independent think-tank, the Pak Institute for Peace Studies.
"Once people find they have a stake in this progress, the need for checkposts and barricades will disappear," said Army Chief General Raheel Sharif this month in Quetta, as he and Prime Minister Nawaz Sharif officially launched a new highway linking the city with Gwadar.
Chinese foreign ministry spokesman Lu Kang said progress so far on the corridor was "generally speaking, quite smooth".
"The Pakistani government has done a great deal of work to protect the security of Chinese organisations and citizens. China is deeply thankful for this," Lu added.
