China is actively expanding its planetary defense capabilities, framing the effort as both a national security imperative and a move to burnish its international reputation. This strategic shift follows a series of policy moves, including China’s 2018 entry into the International Asteroid Warning Network (IAWN) and the Space Mission Planning Advisory Group (SMPAG), both under the United Nations Office for Outer Space Affairs. By the time of its 2021 Space White Paper, Beijing had officially elevated planetary defense to a top policy priority, with explicit goals to enhance monitoring, cataloguing, early warning, and disposal systems for near-Earth objects.
The institutional backbone for these efforts was solidified in 2022 with the creation of the Deep Space Exploration Laboratory (DSEL), an organization led by prominent space engineer and chief designer of the Chinese Lunar Exploration Program, Wu Weiren. The commitment to this field has continued to grow; in February 2025, the government authorized three new specialized roles for planetary defense experts. Shortly thereafter, DSEL hosted a conference on near-Earth asteroid defense involving over 50 domestic experts.
Analysts suggest that these investments serve multiple political objectives. Aligning with President Xi Jinping’s vision of China as a leading space power, these initiatives allow Beijing to portray itself as a responsible actor contributing to a global public good, consistent with its narrative of fostering a “global community of shared future.” Domestically, the program serves as a tool for legitimacy. Public concern, particularly following a 2017 fireball incident over Yunnan Province, has pressured the government to demonstrate its protective capabilities. State media has frequently highlighted these recruitment and research efforts to address widespread social media anxiety regarding asteroid impacts.
Beyond prestige, there is a clear nexus between planetary defense and national security. Many technologies developed for asteroid deflection have dual-use applications, echoing Xi’s 2017 directive to integrate military and civilian development across sectors including outer space. The National Development and Reform Commission has previously identified space infrastructure as a platform for this military-civil fusion. With the 2024 establishment of the Aerospace Force as a branch of the People’s Liberation Army, the military remains the primary authority overseeing these developments, much like how the BeiDou navigation system transitioned from military roots to global commercial utility.
Despite this momentum, Chinese experts have voiced concerns regarding the nation's current limitations. In a 2022 article co-authored by Wu Weiren, researchers acknowledged that China’s influence in the field remains low, noting that Chinese observatories had identified only 32 of the approximately 40,000 near-Earth asteroids catalogued at the time. These experts have consistently called for greater international data sharing and deeper engagement with UN mechanisms. Furthermore, the program faces internal challenges, including an opaque and fragmented governance structure where authority is split among the military, state-owned enterprises, and various government agencies under the final control of the Chinese Communist Party.
As China continues to refine its planetary defense architecture, it is expected to favor high-visibility projects that offer clear strategic or dual-use advantages. However, the combination of restrictive information policies and the integration of these systems into the national security apparatus may continue to limit the extent of Beijing’s collaborative contribution to global planetary defense efforts.
