Internal security has been a governance priority under Xi Jinping. How does China’s budget reflect this prioritization? This research report presents updated data on China’s internal security spending, 1992–2022, revealing a mix of continuity and change. Domestic security expenditure continues to rise, more than doubling from 2012 to 2022, but has risen mostly in proportion to the People’s Republic of China’s overall expenditure. The balance between central and local expenditure has shifted further towards local spending, which, in the context of rising local fiscal constraint, may increase pressure on local public security bureaus. The Ministry of Public Security continues to receive the largest share of domestic security spending, while the proportion of internal security spending allocated to the People’s Armed Police (PAP) has decreased, probably reflecting the reorganization of the PAP in 2017–2018. Spending per capita and relative to GDP continues to be higher in locations that are politically sensitive, including Beijing, Tibet and Xinjiang.
