As for large stationary gas turbines, the Chinese government could counter by speeding up construction of nuclear power plants and turn back on some of the mothballed coal power plants. They can also build more battery storage to cover peaking demands. These people are also so poorly informed they think the highest power Chinese stationary gas turbine is 50MW in power.
As for ball bearings sure the quality of Chinese substitutes would initially suffer, but so what. If the Chinese replaced ballpoints in pens they can replace balls in bearings.
