Is this the technology Clinton transferred to them, or did they get it from someone else?
The stuff I know about is public record. There is a lot of material available on the subject in various books and publications. I'm sure some of what they learned was a consequence of Clinton's transferring technology to them, but much of it is simply available to anyone interested in the subject.
Bill Clinton allowed Loral and Hughes corporations to transfer rocket booster staging and guidance tech to the Chinese, by removing oversight from the Pentagon and transferring it to the Commerce Dept, which was under Ron Brown’s direction at the time. Clinton also allowed the Chinese to get our W88 miniaturization technology. IOW, Clinton committed actual treason; but because many members of Congress were complicit in his treasonous acts, they settled on impeaching him for perjury over a BJ in the oral office.
