Beijing has authorised direct trading between the yuan and Japan's yen - only the second currency after the US dollar to have such an arrangement - as part of a push to internationalise the yuan to become widely used in trade, investment and reserves.
The move, effective from Friday, would lower currency exchange costs, increase the use of the yuan and the yen in trade and investment, and support economic ties, the People's Bank of China (PBoC) said in a statement.
Essentially, this would help to shield market makers from any unnecessary volatility brought by the US dollar, said Raymond Yeung, an economist at ANZ.
He added that the arrangement would also help to develop the onshore foreign exchange market on the mainland.
'It is likely that China will launch more of this direct trade with other countries in the future,' which could erode the influence of the dollar, Yeung said.
The price of the yuan against the yen will be determined by direct quotations offered by market makers on the China Foreign Exchange Trade System based in Shanghai - the forex arm of the central bank.
China has become Japan's largest trading partner. Total trade between the two countries reached 27.5 trillion yen (HK$2.68 trillion) in 2011.
