China's ruling Communist Party has expelled Ma Xingrui, a former member of its powerful Politburo and the former party secretary of the western region of Xinjiang, accusing him of a broad range of offenses including accepting bribes, abusing his power and trading political favors. The party's top anti-graft agency said Ma had "seriously violated" political discipline and referred his case for criminal prosecution; he had been under investigation since April.
Ma is the third sitting member of the 24-seat Politburo — the party's second-highest decision-making tier — to be purged since 2025, an extraordinary rate of attrition for a body whose membership normally turns over only at five-year party congresses. The prior two cases came in October 2025, when General He Weidong, the military's second-ranking officer, and Admiral Miao Hua were expelled in a sweep of the armed forces; He's removal was the first of a sitting Central Military Commission general since the Cultural Revolution.
What makes Ma's case distinct is that it moves the campaign out of the barracks. The 2025 purges were a military affair, targeting the PLA's command structure; Ma was a civilian administrator who had governed a strategically sensitive region and sat at the intersection of industry and provincial power. His fall signals that the anti-corruption drive is now reaching into the civilian leadership pipeline that grooms China's future rulers.
Ma's biography is a particular kind of Chinese elite story. Trained as an aerospace engineer, he spent more than a decade in the country's state-owned space and missile industry, rising to become an executive at China's main spacecraft and missile manufacturer before pivoting into politics — a rocket scientist turned governor turned party boss. That technocratic, industrial background was once seen as a mark of the modern cadre Xi wanted to promote, which makes his expulsion a sharper statement about how far the purge now reaches.
The official charges followed the familiar template: taking bribes, helping family members buy property at a discount, and condoning subordinates' violations. As with earlier cases, the party disclosed the outcome — expulsion and referral for prosecution — without laying out the underlying evidence, and Ma has had no public opportunity to respond.
Analysts read the accelerating cadence of top-level purges two ways. One is that Xi is genuinely rooting out entrenched corruption in the party and army. The other is that anti-corruption remains the instrument through which he removes rivals and enforces loyalty, now more than a decade into a campaign that has outlasted every prediction of its exhaustion. Either way, the message to the remaining members of the Politburo is that no rank, and no résumé, confers immunity.
