The capital adequacy ratio among foreign banks in China rose to 19.74 percent by the end of 2012, from 18.83 percent the previous year. Their core capital adequacy ratio stood at 19.25 percent, in contrast with 18.38 percent at the end of 2011.

"Overall the main indicators of foreign banks are all higher than the regulatory standards, and they are basically in a healthy condition," the CBRC said in the report.

By the end of last year, banks from 49 countries and regions had set up 42 locally incorporated banks, 95 branches, and 197 representative offices in China.

Outstanding loans extended by those banks increased 6.2 percent to 1.04 trillion yuan from one year earlier, while their deposits rose 7.7 percent to 1.43 trillion yuan.
