"China is providing technology that Moscow’s military needs to prosecute the Kremlin’s war in Ukraine despite an international cordon of sanctions and export controls, according to a Wall Street Journal review of Russian customs data.

Those are but a handful of tens of thousands of shipments of dual-use goods—products that have both commercial and military applications—that Russia imported following its invasion last year, according to the customs records provided to the Journal by C4ADS, a Washington-based nonprofit that specializes in identifying national-security threats. Most of the dual-use shipments were from China, the records show."
