On 9 May 2003, the President of the United States outlined a strategy towards the establishment of a U.S.- Middle East free trade area, to be developed within a decade. One step towards this was to be the negotiation of bilateral investment treaties (BITs) and Trade and Investment Framework Agreements (TIFAs) with Middle Eastern countries.

On 7 July 2004, the United States and the Sultanate of  Oman signed a Trade and Investment Framework Agreement (TIFA) as a forum to examine ways to expand bilateral trade and investment. On 15 November 2004, the U.S. Administration notified the U.S. Congress of its intent to negotiate a free trade agreement with Oman. On 12 March 2005 the United States and Oman launched negotiations in Muscat, Oman, and concluded the negotiations on 3 October 2005. The U.S. Administration notified Congress of the intent to sign the FTA on 17 October 2005. The draft text was made available to the public on 18 October 2005. The agreement was signed on 19 January 2006.
