Official contacts between CERN and the Philippines were established in January 2009. There is much enthusiasm in the Philippines for collaboration with CERN. Until now, the contribution of the Philippines to high-energy physics has focused on theoretical physics. However, the official approach to CERN by the Government of the Philippines and by the physics community is very encouraging for the development of scientific collaboration in experimental and theoretical particle physics with CERN.

An Expression of Interest between the Philippines at CERN for scientific, technical and educational collaboration was signed in January 2010 and an Expression of Interest with CMS for collaboration of the LHC was signed in October 2011. CERN and the Philippines signed in International Cooperation Agreement (ICA) in 2018.

Students and teachers from the Philippines participate in the Summer Student programme and the High School Teacher programme

Discussions are progressing for the formation of a sizeable cluster of experimental high-energy physics groups to join CMS.
