So sanction on China is very logical. American give EUV or other advanced tech to China is like America give nuclear weapon/ missile equipment to China so that it can manufacture it and nuke back American and its allies. American is very benevolant to give SMIC/ Cxmt /Ymtc/BOE advanced manufacturing process. If situation is different let say China is more advance than America in semiconductor, China will never share their own technology and done the same thing like america did. America share their technology equipment with taiwan south korea, Japan even though taiwan/korea beat them in semiconductor market. Western country like Germany share their car manufacturing tech to China until China now master how to make a car. Apple build their iphone assembly in China that lead to rise of Huawei, Xiaomi, and HP build their factory in China that lead to rise of Lenovo. Japan company like toshiba give China technology how to make home appliance that lead to rise of hisense,haier, midea and other chinese company. All western/japan company contribute to China economic growth. What China do to return in favor? Nah, lets invade taiwan instead or lets conquer all south china sea. Is China ungrateful? or American and western country abuse their superpower status?
