首先，《联合声明》是中英间关于中国收回香港及有关过渡期安排的重要文件，其中没有任何条款赋予英方干预回归后香港事务的权利，而且涉及英方的条款均已履行完毕。

　　《联合声明》共有8条正文和3个附件。第1条规定中国对香港恢复行使主权，第2条规定英国将香港交还给中国。香港回归后，这两条已同时履行完毕。第3条及附件一是关于中方对香港基本方针政策的原则阐述及具体说明，但没有任何涉及英方权利和义务的表述。第4至6条和附件二、附件三规定两国在回归过渡期的有关安排，包括双方在香港的行政管理、中英联合联络小组的设立和运作、土地契约以及批约等事项。第7、8条是关于实施和生效的条款。这些规定随着香港回归和各项后续工作的完成也都已履行完毕。

Firstly, the Joint Declaration is an important instrument between China and the UK on China's resumption of the exercise of sovereignty over Hong Kong and arrangements for the transitional period. There is no single clause in it that grants the UK any right to interfere in Hong Kong affairs after its return, and all clauses concerning the UK have been fulfilled.

The Joint Declaration consists of eight paragraphs and three annexes. Article 1 is about China's decision to resume the exercise of sovereignty over Hong Kong. In Article 2, the UK states that it will restore Hong Kong to China. These two articles have been fulfilled upon the return of Hong Kong. In Article 3 and Annex 1, China elaborates its basic policies regarding Hong Kong, yet with not the least implication of UK's rights and obligations. Articles 4, 5 and 6 and Annexes 2 and 3 provide for relevant arrangements during the transitional period, including the administration of Hong Kong, the establishment and operation of a Sino-British Joint Liaison Group, land leases and ratification. Articles 7 and 8 are about the implementation and entry into force of the instrument. All these provisions have been fulfilled with the return of Hong Kong and the completion of ensuing work.

　　第二，《联合声明》中的对香港基本方针政策及具体说明，系中方单方面政策宣示，纯属中国内政，不是双方协议内容。《联合声明》第3条明确表示，“中华人民共和国决定在对香港恢复行使主权时，根据中华人民共和国宪法第三十一条的规定，设立香港特别行政区”。这表明，在港实施“一国两制”的法律基础是中国《宪法》，并非基于《联合声明》。

Secondly, the basic policies regarding Hong Kong elaborated in the Joint Declaration were proposed by China on its own and hence are completely China's domestic affairs, rather than an agreement between the two sides. As Article 3 of the instrument clearly states, "The People's Republic of China has decided to establish, in accordance with the provisions of Article 31 of the Constitution of the People's Republic of China, a Hong Kong Special Administrative Region upon resuming the exercise of sovereignty over Hong Kong." It shows that the legal basis of implementing "One Country, Two Systems" in Hong Kong is China's Constitution, instead of the Joint Declaration.

　　第三，《联合声明》更没有任何条款规定英方在香港回归后对香港承担任何责任。英方因《联合声明》产生的与香港的法律联系，最迟在中英联络小组2000年1月1日终止工作时已不复存在。英方无权再根据《联合声明》对香港提出新的权利或者责任主张。简言之，对于回归后的香港，英国一无主权、二无治权、三无“监督”权。

　　特别需要指出的是，《联合声明》只是中英间双边文件，内容不涉及其他国家。根据一般国际法，其他国家和组织更是无权假借《中英联合声明》干涉香港事务。

Thirdly, the Joint Declaration includes no clause that provides for British obligations to Hong Kong after the city's return. All legal relations between the UK and Hong Kong created by the instrument had terminated by 1 January 2000 at the latest, when the Sino-British Joint Liaison Group ceased operation. The UK is not entitled to claim any new rights over or obligations to Hong Kong by citing the Joint Declaration. To be brief, the UK has no sovereignty, jurisdiction or right of "supervision" over Hong Kong whatsoever after the latter returned to China.

It needs to be emphasized that the Joint Declaration is a bilateral instrument between China and the UK and does not concern any other country. According to general international law, other countries and organizations have no right to meddle with Hong Kong affairs on the pretext of the Joint Declaration.
