the only areas where China has invested more money than the US iarein high technology, quantum computers, & nuclear attack submarines. The US owns the air, China owns the sea. The US navy, whilst plumbing the bottom of the South China Sea, seeking trails of the new Chinese nuclear attack subs, were surprised to find a Chinese sub rose to the surface next to the USAs best technology ship, the Chinese sailors came out on the submarine deck and waved to the Americans, and then the sub descended again to be unfindable within a minute by the best US technology. Then, next day, China offered to sell its old sub technology to the USA, to help them out. China's old technology was made by Huawei.
