Some Chinese banks are so fearful of sanctions that they're returning payments for goods that have reached Russia, report says

• Some Chinese banks are returning payments for goods that have reached Russian shores, a report says.
• The US recently imposed new restrictions on 400 entities supporting Russia's war in Ukraine.
• Chinese exporters are said to be requiring pre-payment for goods going to Russia.

The US's tightening sanctions against those aiding Russia's war efforts are really spooking some Chinese banks.
