Several new liner operators appear to be cashing in on high freight rates between China and Russia.
They have launched services to fill a void left by major operators, which have pulled out to avoid problems with sanctions.
The trade is being populated by Chinese newcomers, including OVP Shipping and Safetrans Line.
These are adding to the services of Russian operators such as Torgmoll/Newnew Shipping, while some established Russian companies continue to pick up vessels from the secondhand market.
