"The US Department of Commerce is proposing new regulations that seek to ban the sale of Chinese-[PRC] made cars in the United States, over concerns that they could be used for espionage or sabotage. Several reports on the proposal noted that it was hurriedly introduced last week as a “national security action,” rather than a trade-related dispute between the US and China." This was reported in the US on Sept 23 - a week after bombings against Hezbollah Pagers.
The US Government is balancing Chinese intelligence gathering and sabotage risks against American consumers' demand for low cost Chinese goods, especially cars. This is going
to be a major policy problem which may extend to other Five Eye countries like the UK and Australia.
China pre-positioning or reprogramming software that controls the heat build-up within Large Lithium Batteries in electric vehicles (EVs) that China exports to the US is a serious risk. Unless heating is limited hot Lithium Batteries can explode. Also see this US website. Typical Lithium Batteries in cars weigh between 300 and 1,000 kg. This makes them capable of very large explosions.
This may be analogous to Hezbollah's experience of Israel possibly using software reprogramming to cause explosions of the Lithium Batteries in Pagers on Sept 17 and Walkie Talkies on Sept 18. The US sourced explanation that Israel used plastic explosive in Hezbollah's Pagers and Walkie Talkies may be a deception. Specialised software programming in these devices alone might heat up Lithium Batteries sufficiently to explode.
Also there are problems in all the other electronic consumer goods China exports to the US and Australia being used for intelligence collection and sabotage eg. Laptops see FAA advice (especially those carried by passengers on aircraft), Pacemakers, Printers, Cell-phones, Smart Watches, Smart TVs and Smart Headphones (the last item could damage hearing) etc.
The US also exports many consumer goods which have Lithium Batteries, like iPhones and Tesla cars. Israel may share its exploding battery software with certain allies.
