Pakistan identified Gwadar as a port site as far back as 1954 when Gwadar was still under Omani rule. Pakistan's interest in Gwadar started when, in 1954, it engaged the United States Geological Survey (USGS) to conduct a survey of its coastline. The USGS deputed the surveyor, Worth Condrick, for the survey, who identified Gwadar as a suitable site for a seaport. After four years of negotiations, Pakistan purchased the Gwadar enclave from Oman for free as friendly gift on 8 September 1958 same as Khan of Khalat has gifted it to Omani Prince and Gwadar officially became part of Pakistan on 8 December 1958 back, after many years of Omani rule.
