Sun Yuning, a former deputy head of China's General Administration of Customs, has been expelled from the Communist Party of China and removed from office over corruption, the country's top anti-graft agencies announced on Friday.

The CPC Central Commission for Discipline Inspection and the National Supervisory Commission said Sun had "lost his ideals and convictions, betrayed his original mission, and resisted the investigation."

Authorities first announced on Sept 24, 2024, that Sun was under investigation for suspected serious violations of discipline and law.

An official statement said he had illegally accepted gifts and cash, taken trips that could have compromised his official duties, and frequented private clubs in violation of regulations. He was also accused of interfering in personnel appointments in exchange for money and engaging in money-for-sex transactions.

Sun further "used public power as a tool for personal gain," sought benefits for others in business dealings, and improperly influenced the allocation of public financial funds, according to the statement.

His actions "severely violated Party discipline" and constituted a serious breach of duty-related laws, it said. Sun is suspected of bribery, and his case has been handed over to prosecutors for further legal proceedings.

The decision to expel him from the Party and remove him from public office was approved by the CPC Central Committee, authorities said.
