Barter deals between Moscow and Beijing were not an exception before the collapse of the Soviet Union.
They also continued in the 1990s, but the deals now being discussed would be the first in about 30 years.
Barter trade will allow Russia and China to solve problems with payments, transactions and currency risk, Reuters writes.

Kyle Shostak, vice chairman of Qifa, said Russia and China could develop rules for barter trade.
The document of the Russian Ministry of Economy, developed in February, provides recommendations to companies on conducting barter transactions.
It is also emphasized that barter transactions are a good way to avoid international settlements and cash.
Sources believe that the idea of barter deals solves the problem of paying for sanctioned and civilian goods.
