Oman–Pakistan relations are warm and cooperative. Oman has an embassy in Islamabad and a Consulate-General in Karachi, whereas Pakistan has an embassy in Muscat. Oman is the nearest Arab country to Pakistan, because of this, they both share a maritime boundary with each other. 30% of Omanis are of Balochi origin from Pakistan's Balochistan province, having settled in Oman over a hundred years ago. Gwadar was formerly part of Oman but was sold to Pakistan on 8 September 1958. It was integrated within Balochistan on 1 July 1977 and became a full sub-division of the Gwadar District. There are over 85,000 Pakistani immigrants resident in Oman.
