Improvements in telecommunications infrastructure are a vital component of the Belt and Road Initiative. Communication projects are critical to businesses and economic growth. Pakistan, presently, is connected to world-wide internet traffic via five under-sea fibre optic cables. A submarine cable laid on the sea, connects landing stations along the seaboard in various countries, it is linking to global internet traffic.
Cables connecting Pakistan to world-wide internet also provide a telecommunications link between South East Asia, Middle East, Indian subcontinent and Western Europe. Three more fibre-optic cables are under construction. Pakistan Telecommunications Company Limited. (PTCL) and Transworld Associates Private Limited (TWA) operate Pakistan section of these cables and provide internet and communication services to consumers and businesses across the country. In recent years, with the launch of 3G/4G networks number of internet users in Pakistan have also grown exponentially. These users are generating data traffic which requires setting up of new fibre-optic cables.
