An elite and secretive gathering of senior government officials and captains of industry is wrapping up a weekend confab at the chic Swiss resort of St. Moritz. The annual Bilderberg meeting's Web site said its annual conference ending Sunday dealt mainly with challenges for growth, security and democracy in Europe, the Middle East and China. The 130 attendees from Europe, North America and other countries -- among the invitees were EU President Herman Van Rompuy, members of European royalty, former U.S. Secretary of State Henry Kissinger and Google's executive chairman Eric Schmidt -- keep up an informal, off-the-record tradition that conspiracy theorists consider almost a shadow world government. This year's conference was held at an Alpine luxury hotel patrolled by private security guards that drew a left-wing demonstration Saturday.
