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

Both figures shrank from the $69.6 billion 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 billionto $145.6 billion.

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

The revised capital and financial account surplus narrowed from $67 billion in the second quarter and $86.1 billion 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 in the third quarter, the SAFE said.

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