There have been a series of incidents in the Philippines where Chinese nationals have illegally obtained Philippine citizenship and are active as market or corporate representatives, raising national security concerns. Recently, Lawrence Ke Sai, CEO of Maxifpro Development, a power grid construction company, was revealed to be Chinese, highlighting the threat posed by Chinese nationals entering key infrastructure sectors. This follows the 2024 case of Alice Guo, a Chinese national who disguised herself as a Philippine market participant, and experts are pointing out that nationality theft is recognized as a major route threatening national security. Calls are growing for the Philippine government to strengthen security checks on foreign nationals participating in important infrastructure projects.
