The accuracy of data on China’s national balance sheets has attracted much less attention than that of the Gross Domestic Product reports. China’s Bureau of National Statistics has not released official national balance sheets, but two Chinese research teams have produced estimates for recent years.

The System of National Accounts was claimed by researchers as a common framework, but non-standard classifications and disclosures of assets and liabilities from diverse data sources mean that many issues must be resolved before China’s wealth can be measured accurately.
