SHANGHAI, Nov 22 (Reuters) - China's yuan
The step is part of Beijing's efforts to expand the use of the yuan for trade and even investment purposes, as a way of reducing reliance on the dollar and thereby simplifying the settlement of trade in everything from energy to manufactured goods.
The rouble is the seventh currency traded against the yuan in the China Foreign Exchange Trade System (CFETS).

Russia is also trying to raise the profile of the rouble after the crises of the 1990s and has called for a reduction in reliance on the dollar as a global reserve currency.
A Russian exchange official said last week that Russia would also start yuan/rouble trading in December, after plans for the launch of such trade were unveiled in September. [ID:nLDE68711E]
"China is now vigorously promoting the yuan's use in the region and in the world partly because it is unhappy with the dollar's performance since the latest global financial crisis," said a dealer at a major European bank in Shanghai.
"To achieve that goal, it needs to allow more currencies to trade against the yuan at the CFETS, with the won
SNUBBING THE DOLLAR
The rouble
The yuan will be permitted to rise or fall 5 percent against the rouble each day from the mid-point, CFETS, a unit of the central bank, said in a statement. The Chinese currency is still not freely convertible under the capital account.
The yuan-rouble trading range is the same as that for yuan/ringgit, but is wider than the 0.5 percent the yuan may move against the dollar in either direction each day and the 3 percent leeway allowed against most other currencies.
The wider band for yuan/rouble reflects the greater volatility of currencies of emerging economies, CFETS said.
China, the biggest holder of U.S. Treasuries, has complained about the dollar's volatility since the financial crisis, urging stability of global reserve currencies.
Increasing the number of currencies traded against the yuan will gradually help reduce the dollar's weight in the yuan's nominal real exchange rate (NEER), or the currency's value against a trade-weighted basket, traders said.
Most China-based traders believe that the dollar accounts for about 70 percent in the Chinese NEER system. Many Western analysts believe such a NEER system is still highly correlated to the dollar, although Beijing has persistently said it is using a basket system to price the yuan.
Among other steps to regionalise and internationalise the yuan, China has launched a programme to use the yuan for settlement in exports and imports, and allowed the development of a nascent offshore yuan
Beijing last month also started a pilot programme for allowing some inbound and outbound foreign direct investment in the far western region of Xinjiang to be settled in yuan. [ID:nTOE69T009]
