In 2011, the Pakistani defence minister had announced in Beijing that his country would transfer ownership to a Chinese company. China had demurred then, but despite the worsening security situation in Balochistan, the Chinese have apparently agreed to take it over.
China has already encountered opposition from Baloch people, who have objected to the Chinese taking over their territory.
Gwadar port was built by China but during its operation by PSA, it barely attracted any commercial traffic. There is also a lot of port development that remains to be built.
Pakistan expects China to complete that construction in record time, given its past performance.
