By Daniel Trotta PANAMA CITY (Reuters) – U.S. President Barack Obama and Cuban President Raul Castro will share the same stage on Friday in an encounter rich with symbolism as their countries set aside decades of mistrust and attempt to restore diplomatic relations. Obama and Castro have separate agendas for most of the day but they will both attend the start of the summit along with other regional leaders on Friday evening. Apart from a couple of brief, informal encounters, the leaders of the United States and Cuba have not had any significant meetings since Castro’s older brother Fidel Castro toppled U.S.-backed dictator Fulgencio Batista in a 1959 revolution.
