If China maintains the current relations with the US, it's likely that the US will not sell the cutting-edge technologies to China, but will continue to allow n-1 or n-2 versions to be available to China. This way, the US will maintain the lead and at the same time can monetize the older technologies.
However, once there is a geopolitical event such as China attacking Taiwan, the US for sure will pull the plug and put the Chinese industries in limbo.
