考克斯报告里指出的是中国90年代中期造出W88级核弹头

On Feb. 23, 1994, Los Alamos was host to the highest-level group of Chinese weapons officials ever to visit the United States. Leading the delegation was Hu Side (pronounced se-DUH), the new head of the Chinese Academy of Engineering Physics, the nation's bombmakers. American intelligence officials had learned that he was the designer of China's two-point bomb.

One person not on the guest list was Wen Ho Lee. ''We had very tight controls on access,'' a laboratory official said. ''The door was closed. The session was not advertised.'' But that afternoon, Dr. Lee appeared at a briefing and was warmly greeted by Dr. Hu.

''There is a lot of bowing and exchanging cards,'' another official recalled. He was startled that a midlevel hydrodynamics expert at Los Alamos knew China's top nuclear scientist. And Wen Ho Lee was not simply relatively obscure; just months before, he had learned he might be laid off because of budget cuts.

Then a translator told the official that Dr. Hu was thanking Dr. Lee in Mandarin. ''They're thanking him because the computer software and calculations on hydrodynamics that he provided them have helped China a great deal,'' the translator said.

Laboratory officials informed the F.B.I., which had suspicions of Dr. Lee from Tiger Trap and opened an investigation. Officials did not know what to think. Dr. Lee had never reported meeting Dr. Hu in China. If the two had an improper relationship, why expose it at Los Alamos?

1994年2月23日，洛斯阿拉莫斯迎来了一批中国核武器方面的高级官员，领头的是胡思得，中国工程物理研究院的新院长。中国工程物理研究院是中国负责造核弹的单位。美国情报官员知道他（胡思得）是中国两点内爆式核弹的设计者。
李文和并不在出席名单上。“我们对参会人员控制的很紧”，一个（洛斯阿拉莫斯）实验室官员说道。“门是关着的，这件事并没有公开”。但在那个下午，李博士却出现在了会场，并得到了胡的热情欢迎。
“现场有很多鞠躬、交换名片之类的”，另一位官员回忆到。他对于一个负责研究金属流体力学的中级技术专家，居然和中国首席核武器专家互相认识感到很惊奇。而且，李文和不仅是不出名而已；就在几个月前，他被告知由于预算缩减，他将被解雇。
接着，一个翻译官告诉这位官员，胡正在用普通话向李表示感谢。“他们在感谢李，因为他提供的软件和金属流体力学方面的计算帮了中国很大的忙”，这位翻译官说到。
实验室官员通知了FBI，后者早就对李有怀疑了，并开展了调查，但也感到糊涂：李文和从来没报告过自己去中国时和胡思得见过面；可是如果二人之间存在不正当关系，为啥在洛斯阿拉莫斯这个地方把这个关系公开？
