The envoy said that goods shipped from China can be loaded from trucks to trains from the Havelian land port.

He further said that two sides are working to improve Islamabad's capabilities in land surveying by planning to launch a satellite.

China will also help Pakistan build an international airport in Gwadar and a highway connecting the deep-sea port to the airport.
