China's Anti-Corruption Purge Reaches Space: Senior Defence and Space Official Investigated

.

Space and Arms Official Placed Under Investigation

Beijing's anti-corruption watchdog has opened a formal investigation into one of China's most prominent figures in defence and space administration. Bian Zhigang, deputy head of the State Administration of Science, Technology and Industry for National Defence (SASTIND), is suspected of "serious violations of discipline and law" — the standard official phrase for corruption and bribery.

The investigation was announced jointly by the Central Commission for Discipline Inspection (CCDI) of the Communist Party of China and the National Commission of Supervision. The CCDI is China's most powerful anti-graft body and has spearheaded Xi Jinping's decade-long crackdown on official misconduct.

Bian was appointed deputy head at SASTIND in February 2024. His profile was removed from official government websites shortly after the investigation became public.

A Powerful Agency at the Heart of China's Military Machine

SASTIND is no ordinary bureaucracy. The agency coordinates the research, development and production of weapons and military technology across the nuclear, aerospace, aviation, shipbuilding, armaments and electronics sectors, while also driving the core capabilities of China's defence industrial base.

Beyond his defence role, Bian also served as deputy director of the China National Space Administration (CNSA) — making him one of the country's most visible faces in international space diplomacy. He had publicly championed China's International Lunar Research Station, noting that 17 countries and international organisations as well as more than 50 research institutions had joined the project.

The Purge That Keeps Growing

Bian's case does not stand alone. It is the latest chapter in a sweeping campaign that has reshaped China's entire defence establishment.

Xi Jinping has taken his purge of the armed forces to the very top, with more than 100 officers potentially ousted since 2022. The crackdown has at times paralysed entire command structures.

In May 2026, the campaign reached an unprecedented level of severity. Former defence ministers Wei Fenghe and Li Shangfu were convicted of bribery and handed death sentences with a two-year reprieve — sentences that under Chinese law are typically commuted to life imprisonment. Both men were also stripped of their political rights for life and ordered to forfeit all personal property.

Until those verdicts, no one from the military top brass had received such severe punishments since the early days of the anti-corruption campaign.

Control Through Corruption Charges

Analysts note that the anti-corruption drive serves a dual purpose. While the campaign formally targets corruption, Xi has also used it as a tool to consolidate political loyalty and control among the political elite.

A report by the International Institute for Strategic Studies warned that China's ongoing military corruption purges are leaving serious deficiencies in its command structure and are likely to have hampered the readiness of its armed forces.

The dismissal of top commanders raises urgent questions about the stability and operational effectiveness of one of the world's largest military forces — at a time when Beijing is simultaneously pushing ambitious space and weapons programmes.

What Comes Next

Bian Zhigang has not publicly responded to the investigation. His case now moves through a process that, based on recent precedent, could result in expulsion from the Communist Party, criminal prosecution, and a lengthy prison term — or worse.

For the moment, one of China's leading space diplomats has vanished from the official record. The investigation sends a clear message: in Xi Jinping's China, no sector — not even the agencies reaching for the stars — is beyond the reach of the party's anti-corruption machine.
