Authorities in St Petersburg allegedly discovered 20 to 30 kettles and irons with 'spy microchips that send some data to the foreign server'.
The revelation comes just as the EU launches an investigation into claims that Russia itself bugged gifts to delegates at last month's G20 summit in an attempt to retrieve data from computers and telephones.
This has led to speculation that the chips allegedly found in the home appliances may also have the ability to steal data and send it back to Chinese servers.
The allegations against the Chinese were made in St Petersburg news outlet Rosbalt, which quotes a source from customs broker Panimport, but does not detail what data was being sent or to where.
According to The Register, which translated the article, it would be possible to build a malicious microchip - sometimes referred to as a spambot or spybot - small enough to hide in a kettle.
