In November 2001, two months after Al-Qaeda's terrorist attacks on the United States, Yemen's then-President Saleh visited Washington, D.C., and Yemen subsequently increased its counter-terrorism cooperation efforts with the United States. President Saleh returned to Washington, D.C., in June 2004 when he was invited to attend the G8 Sea Island Summit and agreed to participate in future activities detailed in the Sea Island charter. In November 2005 and May 2007, President Saleh again visited high-level officials in Washington, D.C., including President George W. Bush and Secretary of State Condoleezza Rice.
