The International Civil Aviation Organization (ICAO) is set to hold its 42nd Assembly from September 23 to October 3, 2025, in Montreal, Canada. This triennial event brings together member states, nonmember states, NGOs, and private enterprises to establish global civil aviation regulations and standards. Chen Shih-kai, Minister of Transportation and Communications of the Republic of China (Taiwan), has called for Taiwan’s full participation in ICAO’s Assembly, technical meetings, and mechanisms to address regional aviation safety and development needs. The Taipei Flight Information Region (FIR), managed by Taiwan’s Civil Aviation Administration (CAA), is one of the busiest airspaces in East Asia. Despite its critical role, Taiwan has faced challenges in participating directly in ICAO due to geopolitical tensions. China’s unilateral actions, such as declaring temporary danger zones within the Taipei FIR without proper notice, have compromised flight safety. Taiwan has demonstrated its commitment to aviation safety and sustainability through initiatives like the State Safety Program and the adoption of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). However, Taiwan’s exclusion from ICAO’s technical meetings hinders its ability to access timely information and collaborate effectively. ICAO’s theme for the 42nd Assembly, “Safe Skies, Sustainable Future,” underscores the need for inclusivity. Taiwan’s participation is essential to achieving ICAO’s vision of a resilient, sustainable, and inclusive international aviation system.
