China on Wednesday lowered its third-quarter current account surplus to 53.4 billion U.S. dollars from the preliminary figure of 57.8 billion U.S. dollars.

Both figures shrank from the 69.6 billion U.S. dollars registered in the second quarter of 2011.

The State Administration of Foreign Exchange (SAFE) also trimmed its previously announced figure for the first three quarters from 141.2 billion U.S. dollars to 145.6 billion U.S. dollars.

However, the SAFE doubled the capital and financial account surplus from the previous estimate of 33.9 billion U.S. dollars to 66.2 billion U.S. dollars.

The revised capital and financial account surplus narrowed from 67 billion U.S. dollars in the second quarter and 86.1 billion U.S. dollars in the first three months of last year.

The surpluses under the current as well as capital and financial accounts raised the country's international reserve assets by 91.7 billion U.S. dollars in the third quarter, the SAFE said.

The foreign exchange reserves increased 92.1 billion U.S. dollars during the July-September period, excluding effects of changes in the exchange rate and asset prices.
