澳门主权问题的提出主要是在中国鸦片战争失利以后。１８６２年条约是葡人居澳以来中葡两国签订的第一个条约。由于葡萄牙代表在议约中采取了欺诈手段，清政府未予批准。自１８６４年换约失败至１８８７年条约谈判之前的２０余年时间里，葡萄牙为了以订立条约的形式达到＂合法＂占据澳门的目的，曾经串通列强及其驻京公使，多次与清政府进行交涉。 The issue of the sovereignty of Macao is mainly after the defeat of the Opium War in China. The 1862 treaty is the first treaty signed between China and Portugal since the Portuguese lived in Macao. As the representative of Portugal took fraudulent means in the treaty, the Qing government did not approve it. For more than 20 years prior to the 1887 treaty negotiation, Portugal, in order to reach the goal of “lawful” occupation of Macao in the form of a treaty, has colluded with the powers and its Beijing delegation to negotiate with the Qing government on many occasions. .
