2016年10月，在松竹梅联盟创建三校--北大、清华、交大--校友会倡议和推动下，“南加州中华高校校友会联盟”（以下简称“高校联盟”，英文名：Chinese University Alumni Association Alliance of Southern California, 缩写CUAAASC）正式成立。是一个跨两岸三地的多所高校校友会联合组成的非盈利机构。
In October 2016, the Song-Zhu-Mei Alliance original members of three universities -- Beijing University, Tsinghua University, and Chiao Tung University initiated to establish an Alliance to include a greater number of Chinese University Alumni Associations in Southern California. Then the new Alliance organization, named as Chinese University Alumni Association Alliance of Southern California
(CUAAASC), was founded.
The purposes of the establishment of the Alliance are to construct a bridge for communications among the Chinese university alumni in Southern California, to provide help to each other, and to exchange information with each other. Establishment of the Alliance is significant to (1) fulfill the needs of assisting the alumni of universities in employment, entrepreneurship, life styles, sports activities, socializing, and others; (2) gather the strengths of the alumni families with the help of collective efforts to build this new alumni organization into a Southern California reputable overseas Chinese organization in collaboration with other local Southern California overseas Chinese associations; and (3) provide a strong platform for alumni of universities from the overseas Chinese, especially those from mainland China to visit the United States for exchange, business and collaboration. In the meantime, the Alliance is also promoting growth and progress of its own. The Alliance currently has 65 members coming from respective university alumni associations.
