Project Pengyou, begun by Holly Chang in May 2011, is a non-governmental social venture. Project Pengyou serves to build the alumni network of President Obama's 100,000 Strong Initiative in order to promote US-China relations. Project Pengyou is a programme of the Golden Bridges Foundation, a non-profit organisation that pioneers excellence in social entrepreneurship and philanthropy between China and the United States. The organisation provides an opportunity for Americans who have lived or studied in China to share their unique experiences with one another and remain in contact.
