Francis Chao, founder and managing director of Uniworld, LLC has been the organizer for the China General Aviation Forum since 2002. This annual event has brought hundreds of Chinese and International GA operators, suppliers, consultants, and Governmental representatives under one roof to meet and discuss how to expand General Aviation in China. Many cooperative arrangements between local and international General Aviation companies have been established due to the China GA Forum.

Mr. Chao’s contributions to China’s general aviation development and his unique role in helping China interact with its international counterparts has been recorded in detail in the book “China Airborne” by James Fallows, published in May 2012.
