No, because high quality development focuses on innovation, sustainability and green development instead of raw growth via low quality development (construction, low-end manufacturing etc.) They could ramp up low quality development faster and thus achieving higher growth rates in the short term. But they are focusing on long term strategic goals.
China just retaliated by issuing export restrictions for some rare earths, which is an indicator that they are rapidly approaching self sufficiency in many aspects. There are still some major hurdles(EUV alternatives, high end AI accelerators, software stack) but if the current speed of development is any indication, then these too will be overcome and probably much faster than many anticipate.
