You should know that what China is doing was tried in the past. It is an old story. When the microchip was brand new (invented in the USA) the Soviets realized they needed the tech for military purposes. So they built a closed city devoted to silicon research called Zelenograd. It was staffed with very bright physicists and engineers.
But Zelenograd didn't make the Soviets a computing superpower. In fact they were always behind and fell further and further as time went on. The reason is that the Zelenograd scientists were given copies of US chips and told to clone them. By the time they finished cloning one chip the US had already invented several that were much more advanced. Unable or unwilling to forge their own path, even though they were smart enough to do so, they could not truly develop the in-house expertise needed to match the ever accelerating pace of innovation.
The Soviets never did catch up. Americans tightened security and they just fell ever further behind. By the 1980s they did not even have any attempt to develop an internal internet.
That China is running secret projects to try and clone ASML's machines isn't surprising because for all it has changed, it's still a communist state and its leaders still think in communist ways. They don't understand or appreciate distributed wisdom, so are mentally unable to truly understand how innovation works. Government projects like that are destined to fail - they will clone yesterday's machines tomorrow, and just like the Soviets, will fall further and further behind.
The thing that saves China is that its private sector actually does exist and is much more developed, so the Chinese government projects aren't the only way it can make progress.
