How do you come to this conclusion? If China was not "putting it's whole country's effort to make this happen", then Ms Tu's work will be delayed, but hopefully the funds can now go into some other research. But does that necessarily mean "much more to science" in the net outcome?
Referring to the historical context, Mao just introduced the Revolution at that time. As a consequence research institutions and universities were shut down, and scientists and intellectuals were sent to villages to be "re-educated" by farmers. Later Ho Chi Minh asked Mao for medical help for malaria, and Mao assembled 600 scientists who were still available, including Ms Tu, to start a military research project.

If the Cultural Revolution did not happen, most of the scientists in China at that time would be doing their own research, instead of being banished, humiliated and tortured. And Ms Tu would have more colleagues and a better scientific environment to work with.
Additionally, the project that she was working with, Project 523, was kept secret for over a decade. So Ms Tu couldn't communicate with colleagues in other countries regarding her discoveries, and her discoveries in fact were initially published anonymously, further making it difficult for discussion and collaboration. So yes, the amount of net scientific progress was greatly diminished.
