Chinese regional banks that were once vital for processing Russian payments are now rejecting these transactions due to fears of secondary sanctions.
This has led to the emergence of alternative methods, such as cryptocurrency and barter, to support trade between Russia and China.
The smooth flow of Russia-China trade is now disrupted as Chinese regional banks are suspending RMB transactions from Russia. 
The change, according to Izvestia, follows a pattern of banks backing down for fear of being hit with secondary sanctions. Atvira's Ekaterina Kizevich confirmed that her bank had been notified of the suspension in July.
Russian firms are exploring options such as using branches of Russian banks in China, although this could increase costs by up to 5%. Barter trade is also being considered, although this is not possible for all goods.
Cryptocurrencies are becoming a key solution as stablecoins have been used by Russian metal producers to transact with Chinese suppliers since June.
