History of the U.S.-Oman Relationship

The United States and the Sultanate of Oman: Two Centuries of Friendship

The friendship between the United States and Oman dates back over two hundred years when the American ship, the Boston Rambler, sailed to the port of Muscat in 1790.

Formalizing Relations

The two countries formalized their relationship when they signed the “Treaty of Amity and Commerce” in 1833 — the first bilateral accord between the U.S. and an Arab Gulf state. In 1840, the Sultan’s envoy Ahmad bin Na’aman sailed to New York on the Sultanah, and bin Na’aman became the first Arab diplomat accredited to the U.S. The Sultanah was also the first Arab ship to sail to the United States. In 1880, the U.S. established its first Consulate in Muscat in order to strengthen political and economic ties with Oman.

The Twentieth Century

Oman and the United States expanded their trade and diplomatic relations in 1958, when they signed the “Treaty of Amity, Economic Relations, and Consular Rights” in Salalah. In 1972, the United States opened its Embassy in the capital of Muscat and the Sultanate opened its embassy in Washington D.C. the following year. Oman and the United States signed a military cooperation agreement In 1980, which was revised and renewed in 2010, continuing its close military partnership

An Enduring Relationship

Today, the United States and Oman continue to have permanent diplomatic missions in their respective capitals with official delegations regularly visiting both countries. The friendship and relationship between the United States and Oman continues with a bilateral Free Trade Agreement, signed in 2006 and put into effect in 2009, promoting trade and investment in both countries. In 2016, the United States and Oman signed the U.S.-Oman Science and Technology Cooperation Agreement further expanding bilateral cooperation.

Recent visits by the Secretary of State and other U.S. government leaders highlight the long and storied friendship between our two nations. We look forward to many more years of cooperation and collaboration on the important issues that impact both of our countries.
