Diplomatic relations between the Philippines and the Sultanate of Oman were officially established on 06 October 1980, with the Philippine Ambassador to Riyadh being accredited as the country’s non-resident Ambassador to Muscat.
The Filipino population in Oman during this time was about 1,000 to 2,000. Towards the end of the 1980s, the increasing number OFWs in Oman had made it expedient to have Philippine government representation in the Sultanate to attend to the welfare and needs of Filipino workers. Thus, in November 1988, Mr. Essah bin Mohammed Alessa Al Zedjali, a prominent Omani businessman and Editor-in-Chief of the Times of Oman, was appointed the Philippine Honorary Consul General in Muscat.
He served until October 1992. In March 1992, in view of the significant increase in the number of overseas Filipinos in the Sultanate, the Philippine government opened a resident Embassy in Muscat, with Consul Bahnarim Guinomla as Charge d’Affaires, a.i. The following year (1993), Ambassador Sanchez A. Ali became the first resident Philippine Ambassador.
H.E. Munther Mahfoodh Salem Almantheri is the current Omani Ambassador to the Philippines.
H.E. Narciso T. Castañeda is the current Philippine Ambassador to Oman.
