What year did Russia begin using Chinese renminbi in it 's transcations ?
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 .
