To transfer money from Russian to China, you need to know the remittance path of relevant overseas remittances at the bank where the payee is located (you can consult the bank with the payee, and there should be relevant leaflets). Of course, you can't remit rubles to China. Remittances in Russia should be converted from Russian banks into dollars or euros and remitted back to China. Because there is no ruble position in China, it is impossible to make relevant settlement. When the payee receives US dollars or euros, or other large currency, the payee can go to the bank to settle foreign exchange with his ID card.
