They already solved potential problems with oil, and I think they will solve potential problems with food without much problems. Really, US will be just excluded from equation on the China side. US as a market will be exchanged to the markets of all other countries that will become available as soon as US stop extract wealth from international trade using US dollar as currency. World will buy China goods, China will buy food and resources providing money to others to buy Chineese goods.

From technical side, for China it does not matter, what smartphone to assemble - iPhone, Xiaomi or Huawei or other Chineese brands. For South America, Africa, Russia, India and Middle East does not matter what smartphone to buy iPhone or Chineese brands. But chineese smartphones will be cheaper for buyers and China will get more profit assembling them. There is no any sense for some unknown reason pay a huge part of phone price to US for manufacturing and consuming iPhones. And both parties of that smartphone trade will be wealthier just because US will get nothing.

And don't even begin with IP and patents crap. Nobody cares about that US scam.

So no, China will have enough food oil and jobs. May be even more than they have now.

US is only 300M customers. There are much more in the world, but it is US "dollar tax" that make the world too poor to be as good as 300M US customers. Getting rid of dollar will create much more wealthy customers around the world than this limited 300M US customers. So it is very profitable for the China to destroy US dollar and kick US out of world trade.
