The State Administration of Foreign Exchange said on Tuesday that overseas financial assets reached $5.65 trillion at the end of September.
Total debt held by foreign creditors was $3.85 trillion, resulting in a net asset of $1.8 trillion.
Analysts said the assets were mainly held by monetary authorities, whereas the private sector holds most of the debt. The mismatch means losses for the nation, against a background of rapid yuan appreciation and capital account controls.
