（1999年5月31日）
女士们、先生们：
以考克斯为代表的美国一些反华政客，经过半年多时间的精心策划，炮制了一份冗长的所谓调查报告，于今年5月25日公开出笼。这篇报告把中国自力更生、独立自主发展起来的国防尖端技术和关系到国民经济发展的重大科学技术都污蔑为从美国“窃取”或非法“获得”。对这种捏造事实、颠倒黑白、无中生有、捕风捉影的攻击，中国政府和中国人民表示极大的愤慨。
《考克斯报告》断言，“中华人民共和国利用各类人员、组织机构和手段获取美国的敏感技术，中国的科学家、学生、商人和官员以及职业情报人员对美国国家安全构成威胁。”这是对中华民族的极大污蔑，是典型的种族偏见。中国是有着悠久文明历史的大国，中华民族是勤劳智慧的民族，中国历来依靠自己的力量办自己的事情。中国过去没有、现在没有、将来也不会依赖“窃取”别人的技术来发展关系到国家安全和民族利益的重大国防尖端技术。中国国防科技的发展立足于自主开发，这是中国一贯坚持的基本方针。
众所周知，在美国对中国进行全面封锁和核讹诈的年代，中国依靠自己的力量发展了“两弹一星”等国防尖端技术。在中美建交前15年，1964年6月29日中国就成功发射了第一枚自行研制的地地导弹，同年10月16日中国又成功爆炸了第一颗原子弹；在中美建交前12年，1967年6月17日中国就爆炸了自己的第一颗氢弹；中美建交前9年，1970年4月24日中国成功发射了自己的人造地球卫星。这些事实表明，中国完全有能力自主开发任何国防尖端技术。考克斯等美国一些反华政客无视这一事实，极力贬低并否定中国人民开发国防尖端技术的创新能力。
《考克斯报告》对中国的航天事业也进行了大量的歪曲。中国航天事业开始于西方国家禁运和封锁的时代。中国航天事业完全是依靠自己的力量发展起来的。中国的中近程导弹、远程火箭、潜艇水下发射固体燃料火箭、返回式卫星、一箭多星、地球静止轨道通信卫星都是在没有任何外国帮助下独自完成的。1985年，中国宣布进入国际商业卫星发射市场时，已经具备了高、中、低三种轨道各类卫星的发射能力，积累了20次成功发射的经验。1990年，中国首次进行国际商业卫星发射，长征三号运载火箭发射休斯公司制造的亚洲一号卫星，其入轨精度是该公司31颗同类卫星中入轨精度最高的。上述事实均表明中国航天技术已跻身于世界航天先进行列。
商业卫星发射是空间技术的和平运用，是互惠互利的正常商务活动。《考克斯报告》诬称，中国通过商业发射“获取”了美国的制导技术并推进了中国导弹的发展。这完全是一种移花接木、欺世惑众的说法。尽管中国早已拥有高精度的导弹制导技术，但稍具科技常识的人都知道，商业卫星发射决定了只需要采用精度适中、经济合理的制导系统，而没有必要采用弹道导弹那样高精度的制导系统。通过商业发射能提高导弹制导精度，如果是外行人这么说还可以理解，但出自美国国会专门委员会的所谓调查报告，就太令人惊诧了。《考克斯报告》用大量篇幅渲染1995年和1996年中国两次商业卫星发射故障，认为故障原因的判定都是在美国专家指点下完成的，中国因此改进了运载火箭技术并用于导弹，简直是无稽之谈。火箭是中国自行研制的，各种飞行数据在中国人手里。中国人有自行研制火箭30多年的历史，经历过无数次成功与失败，难道排除故障还需要别人指点吗？况且中国人的火箭设计细节，当然也不能轻易向外人泄漏，美国人不知底里，又如何指点？中国既然有能力独立成功地研制运载火箭，当然有能力解决飞行中的技术问题。中国从来没有、也没必要通过故障调查“获取”美国敏感技术。
中国将坚定不移地坚持以经济建设为中心，坚持改革开放，坚持独立自主的和平外交政策。中国是个爱好和平的国家，中国发展自己的科学技术事业，发展自己的国防力量，是为了捍卫自己的国家安全和民族利益，维护国家主权，维护世界和平。中国反对霸权主义，中国永远不称霸。

Chinese Surfer Downloads U.S. Nuclear Data
By Michael Laris, Special to Washington Post
Tuesday,June 1,1999
The demonstration, put on by China's State Council, or cabinet, was part of the government's most aggressive attempt yet to discredit an American congressional report released last week that accuses China of stealing U.S. nuclear secrets during the past two decades.
Zhao Qizheng, spokesman for the State Council, repeated China's long-standing insistence that it has never stolen American nuclear technology. He also leveled accusations of racism and arrogance at Rep. Christopher Cox (R-Calif.) and the other members of a bipartisan select committee, saying their report was an effort to diminish the outstanding work of China's bomb and missile makers, who need no help from the United States.
But Zhao went beyond the standard denials, telling Chinese and foreign reporters that the information China is accused of stealing – including critical design information on the W-88 warhead and six others – has long been openly available in the United States. He cited in particular the Nuclear Weapons Databook series published by the Natural Resources Defense Council.
"Moreover, in recent years, performance data about various types of nuclear warheads, ranging from the early MK-1 [the type of weapon used against Hiroshima in 1945] to the latest W88, can easily be found on the Internet," he said. "They are no longer secrets, so there is nothing to steal."
Zhao refused to any answer questions before relinquishing the stage to Fang, of the China Internet Information Center, a government body that tracks Internet activity in China.
Fang logged on to the Internet and immediately bounced to the Web page of the Federation of American Scientists, a Washington-based group concerned with weapons proliferation and other issues. The federation was founded by scientists who worked on the Manhattan Project and disseminates detailed information on nuclear weapons to encourage public debate on disarmament.
The results of Fang's efforts, including a list of every U.S. nuclear weapon and its specifications, were projected on a large screen. He then searched for W88. Up popped the explosive yield, weight, length and diameter of the warhead, as well as a description of the specific materials used and its key design features.
Fang said he and several other Internet buffs thought of searching for nuclear information on the Internet after reading the Cox report last Wednesday. They also found academic bulletin boards used by American scientists to be great sources of detailed information on U.S. nuclear weapons, he said.
Charles Ferguson, a senior research analyst at the federation and a nuclear expert, said the information on his organization's site could be useful to China. But he disputed the suggestion that there is no difference between what is available in public and secret information, such as nuclear test data.
The site provides "a wealth of information on nuclear weapons, but we don't have a manual for how to produce them or anything like that," Ferguson said.
"There are thousands of parts in the most advanced nuclear weapons," he added. Just knowing "the basic components, what goes into the primary part of it, what goes into the secondary part of it . . . is not enough to give someone the blueprint to develop these things."
