The China Securities Journal, one of the most authoritative financial newspapers in the state-run press, reported the potential moves by the People's Bank of China in a front-page story.

The report said there was an urgent need to widen the trading band -- the yuan is allowed to move 0.3 percent on either side of a daily mid-point set by the central bank -- for a wide range of trade and economic reasons.

"China's trade surplus has hit record highs in the three consecutive months to July, making the need to further expand the yuan trading band an urgent matter," the paper said, citing an unnamed analyst.

China's trade surplus soared over 40 percent year-on-year to 14.61 billion dollars in July, bringing the seven-month figure to 75.95 billion dollars, up nearly 52 percent from the same period in 2005.

China's continually ballooning surplus is one of the biggest causes of trade frictions with its trading partners.

The European Union, Japan and especially the United States claim that China's weak currency gives Chinese exporters an unfair advantage and have repeatedly called for Beijing to raise the value of the yuan.

The China Securities Journal added that "a wider trading band could also be an effective way to ease the problem of excess liquidity".

"It could also curb speculative trading on the foreign exchange market," the paper said.

The report comes at the end of a week that has seen the strongest fluctuations in the yuan's trading band since it was introduced in July last year when the government ended the currency's decade-long peg to the dollar.

The yuan ended at 7.9686 to the dollar in the over-the-counter market Thursday, compared with close of 7.9885 the previous day.

It posted a record rise for a single day on both the over-the-counter and exchange-traded market on Thursday.
