China achieved "relatively good" yields from its management over foreign exchange reserves in the past two years, a central bank vice governor said Tuesday.

China has fully considered risk control in the allocation of the currencies and assets, and high-risk products such as subprime mortgages and collateralized debt obligations are not among China's investment list, said Yi Gang, vice governor of the People's Bank of China.

Yi, also director of the State Administration of Foreign Exchange, made the remarks at a press conference on the sidelines of the annual session of the National People's Congress, the country's top legislature.

China's foreign exchange reserves stood at US$2.3992 trillion at the end of 2009, an increase of US$453.1 billion year on year.
