2011 the government agreed to lift restrictions and to promote the use of business and personal aviation. China's first fly-in was to be held 20–24 September 2011 in Beijing as part of a five-day conference on general aviation, but the fly-in was "postponed indefinitely" due to a Beijing Police Department helicopter crash that raised safety concerns. Switzerland's fly-ins include the one from La Côte, near Prangins, which was held each every 2 years since 2007, organized by the local air-club "Club Aéronautique Swissair Genève" (CASG).
