“It is still an ongoing project. It is not complete. So, by bringing in China means that we can ensure investment on the infrastructure, we can ensure investment on the up gradation and completion of the project,” said Rehman.

Many critics in Pakistan remain skeptical that anyone will be able to make Gwadar economically viable, given the instability and poverty of surrounding Baluchistan province. They say just building the road and rail links to the port could take years - if they are ever built at all.

Ishaq Baloch, a senior nationalist leader in Baluchistan, said federal authorities never consulted with local officials on the deal with China.

“When you will not give the sense of ownership to the native people, they will oppose the mega projects. They will oppose such economic activities if they are not getting benefit from them, and we have a very bitter experience about [previous projects run by] China [in Baluchistan]" said Baloch.

Independent analysts, like former ambassador Arif Ayub, say Pakistani policy makers long have warned about the challenges of developing the Gwadar port. He said handing control to China may not yield any economic benefits.

“It is purely a white elephant [expensive business venture without value], which we are trying to wash our hands of [get rid of],” said Ayub.

In India, officials have called China's role in the port “a matter of concern” because of suspicions it will be used by the Chinese Navy.
