Question: What year did Russia begin using Chinese renminbi in it's trade?
About the article "China", section "Internationalization of the renminbi".

Candidate passages:
In November 2010, Russia began using the Chinese renminbi in its bilateral trade with China.
This was soon followed by Japan, Australia, Singapore, and the United Kingdom.
As a result of the rapid internationalization of the renminbi, it became the eighth-most-traded currency in the world in 2013.
Renminbi hubs outside China.
In 2013, London accounted for over 60% percent of all renminbi-denominated trade activity outside Chinese territory, with daily volume rising to £3.1 billion. 
International use.
International trade.
Before 2009, the Chinese renminbi had little to no exposure in the international markets because of strict government controls by the central Chinese government that prohibited almost all export of the currency, or use of it in international transactions.
Transactions between Chinese companies and a foreign entity were generally denominated in US dollars.
With Chinese companies unable to hold US dollars and foreign companies unable to hold Chinese yuan, all transactions would go through the People's Bank of China.
Once the sum was paid by the foreign party in dollars, the central bank would pass the settlement in renminbi to the Chinese company at the state-controlled exchange rate.
In June 2009 the Chinese officials announced a pilot scheme where business and trade transactions were allowed between limited businesses in Guangdong and Shanghai municipalities and only counterparties in Hong Kong, Macau, and select ASEAN nations.
Proving a success, the program was further extended to 20 Chinese provinces and counterparties internationally in July 2010, and in September 2011 it was announced that the remaining 11 Chinese provinces would be included.
In steps intended to establish the renminbi as an international reserve currency, China has agreements with Russia, Vietnam, Sri Lanka, Thailand, and Japan, allowing trade with those countries to be settled directly in renminbi instead of requiring conversion to US dollars, with Australia to follow soon. 
Speaking after the 2009 G-20 London summit, Gordon Brown announced "the Washington Consensus is over".
There is now broad agreement that large imbalances between different countries do matter; for example mainstream U.S. economist C. Fred Bergsten has argued the U.S. deficit and the associated large inbound capital flows into the U.S. was one of the causes of the financial crisis of 2007–2010.
Since the crisis, government intervention in BOP areas such as the imposition of capital controls or foreign exchange market intervention has become more common and in general attracts less disapproval from economists, international institutions like the IMF and other governments.
In 2007, when the crises began, the global total of yearly BOP imbalances was $1680 billion.
On the credit side, the biggest current account surplus was China with approx.
$362 billion, followed by Japan at $213bn and Germany at £185 billion, with oil producing countries such as Saudi Arabia also having large surpluses.
On the debit side, the US had the biggest current account deficit at over $1100 billion, with the UK, Spain and Australia together accounting for close to a further $300 billion.
While there have been warnings of future cuts in public spending, deficit countries on the whole did not make these in 2009, in fact the opposite happened with increased public spending contributing to recovery as part of global efforts to increase demand.
The emphases has instead been on the surplus countries, with the IMF, EU and nations such as the U.S., Brazil and Russia asking them to assist with the adjustments to correct the imbalances.
Economists such as Gregor Irwin and Philip R. Lane have suggested that increased use of pooled reserves could help emerging economies not to require such large reserves and thus have less need for current account surpluses.
Writing for the FT in Jan 2009, Gillian Tett says she expects to see policy makers becoming increasingly concerned about exchange rates over the coming year.
In June 2009, Olivier Blanchard the chief economist of the IMF wrote that rebalancing the world economy by reducing both sizeable surpluses and deficits will be a requirement for sustained recovery.
In 2008 and 2009, there was some reduction in imbalances, but early indications towards the end of 2009 were that major imbalances such as the U.S. current account deficit are set to begin increasing again.
Japan had allowed her currency to appreciate through 2009, but has only limited scope to contribute to the rebalancing efforts thanks in part to her aging population.
The euro used by Germany is allowed to float fairly freely in value, however further appreciation would be problematic for other members of the currency union such as Spain, Greece and Ireland who run large deficits.
Therefore Germany has instead been asked to contribute by further promoting internal demand, but this hasn't been welcomed by German officials.
China has been requested to allow the renminbi to appreciate but until 2010 had refused, the position expressed by her premier Wen Jiabao being that by keeping the value of the renmimbi stable against the dollar China has been helping the global recovery, and that calls to let her currency rise in value have been motivated by a desire to hold back China's development.
After China reported favourable results for her December 2009 exports however, the Financial Times reported that analysts are optimistic that China will allow some appreciation of her currency around mid-2010.
In April 2010 a Chinese official signalled the government is considering allowing the renminbi to appreciate,but by May analysts were widely reporting the appreciation would likely be delayed due to the falling value of the Euro following the 2010 European sovereign debt crisis.
China announced the end of the renminbi's peg to the dollar in June 2010; the move was widely welcomed by markets and helped defuse tension over imbalances prior to the 2010 G-20 Toronto summit.
However the renminbi remains managed and the new flexibility means it can move down as well as up in value; two months after the peg ended the renminbi had only appreciated against the dollar by about 0.8%.
By January 2011, the renminbi had appreciated against the dollar by 3.7%, which means it's on track to appreciate in nominal terms by 6% per year.
As this reflects a real appreciation of 10% when China's higher inflation is accounted for, the U.S. Treasury once again declined to label China a currency manipulator in their February 2011 report to Congress.
However Treasury officials did advise the rate of appreciation was still too slow for the best interests of the global economy.
In February 2011, Moody's analyst Alaistair Chan has predicted that despite a strong case for an upward revaluation, an increased rate of appreciation against the dollar is unlikely in the short term.
And as of February 2012, China's currency had been continuing to appreciate for a year and a half, while drawing remarkably little notice.
While some leading surplus countries including China have been taking steps to boost domestic demand, these have not yet been sufficient to rebalance out of their current account surpluses.
By June 2010, the U.S. monthly current account deficit had risen back to $50 billion, a level not seen since mid-2008.
With the US currently suffering from high unemployment and concerned about taking on additional debt, fears are rising that the US may resort to protectionist measures. 
The renminbi yuan has different names when used in minority regions.
When used in Inner Mongolia and other , a yuan is called a tugreg ( "tügürig").
However, when used in the republic of Mongolia, it's still named yuani () to differ it from Mongolian tögrög ().
One Chinese tügürig (tugreg) is divided into 100 mönggü (), one Chinese jiao is labeled "10 mönggü".
In Mongolian, renminbi is called aradin jogos or arad-un jogos ( "arad-un ǰoγos").
When used in Tibet and other , a yuan is called a gor ().
One gor is divided into 10 gorsur () or 100 gar ().
In Tibetan, renminbi is called mimangxogngü () or mimang shog dngul.
