During World Youth Day 2008 in Sydney, tensions flared between the 800 Vietnamese pilgrims who used the flag of the Socialist Republic of Vietnam and the 2300 Vietnamese Australians pilgrims who used the Republic of Vietnam flag.[15] In 2008, many protested against Nguoi Viet Daily News, a Vietnamese-language newspaper in Orange County, California, for publishing a photograph of an art installation[16] depicting a foot spa bearing the colors of the flag.[17] In October 2014, the Vietnamese Student Association chapter at the University of Arizona discovered that the University had removed the South Vietnamese flag from the campus bookstore's Flag Display (which includes flags from all over the world to celebrate the diversity found among students).
