In 2015, it was announced that the city and port would be further developed under CPEC at a cost of $1.62 billion, with the aim of linking northern Pakistan and western China to the deep water seaport. The port will also be the site of a floating liquefied natural gas facility that will be built as part of the larger $2.5 billion Gwadar-Nawabshah segment of the Iran–Pakistan gas pipeline project. Construction began in June 2016 on the Gwadar Special Economic Zone, which is being built on 2,292-acre site adjacent to Gwadar's port. In late 2015, the port was officially leased to China for 43 years, until 2059.
