The Taiwan Coast Guard Administration (CGA) safeguards Taiwan's maritime interests. It operates as a law \_41\_ agency under the Ocean Affairs Council. The CGA was formed on February 1, 2000. This formation occurred \_42\_ the merging of multiple agencies. Its main objective is the security of Taiwan's coastline and surrounding waters. Key commitments of the CGA include protecting Taiwan's territorial waters. It also focuses on preventing illegal activities such as \_43\_ and illegal immigration. Conserving marine ecosystems is another key commitment. \_44\_, this agency responds to search and rescue operations. It also ensures the safe and \_45\_ use of the seas. This is achieved by upholding maritime laws and regulations. There have been several notable incidents in Taiwan involving Coast Guard law enforcement actions, including arrests and prosecutions. For example, in June 2024, a 60-year-old Chinese man, surnamed Ruan, entered Taiwan aboard a speedboat via the Tamsui River, raising national security concerns. According to reports, Ruan was a former captain in China's navy and managed to bypass several layers of maritime defense before being intercepted by Taiwan's Coast Guard near Taipei Harbor. Upon his arrest, authorities found he lacked legal documentation for entry. He was subsequently detained and investigated by prosecutors for illegal entry under Taiwan's immigration laws. In court, Ruan admitted to entering Taiwan without authorization and was sentenced to eight months in prison. The incident sparked a broader debate over Taiwan's coastal security measures and prompted the Coast Guard Administration to review and tighten patrol operations in sensitive maritime areas.
