Since becoming a presidential retreat, Camp David has served as the site for diplomatic meetings between the POTUS and foreign heads of state. For example, in September 1978, President Jimmy Carter facilitated a meeting between Egyptian President Anwar El Sadat and Israeli Prime Minister Menachem Begin. The three world leaders spent three weeks at Camp David where they made secret peace agreements; The Camp David Accords were signed by El Sadat and Begin on September 17, 1978. More recently, President George W. Bush hosted a number of dignitaries at Camp David, including President of Russia Vladimir Putin (2003), British Prime Minister Gordon Brown (2007), and Danish Prime Minister Anders Fogh Rasmussen (2006). President Barack H. Obama chose the site to host the 38th G8 summit in 2012, and the GCC Summit in 2015.
