"The explanation for capturing the vessel is perhaps to be found in Barroes’ remark: ‘It is true that there does exist a common right to all to navigate the seas and in Europe we recognize the rights which others hold against us; but the right does not extend beyond Europe and therefore the Portuguese as Lords of the Sea are justified in confiscating the goods of all those who navigate the seas without their permission.’ Strange and comprehensive claim, yet basically one which every European nation, in its turn, held firmly almost to the end of Western supremacy in Asia. It is true that no other nation put it forward so crudely or tried to enforce it so barbarously as the Portuguese in the first quarter of the sixteenth century, but the principle that the doctrines of international law did not apply outside Europe, that what would be barbarism in London or Paris is civilized conduct in Peking (e.g. the burning of the Summer Palace) and that European nations had no moral obligations in dealing with Asian peoples (as for example when Britain insisted on the opium trade against the laws of China, though opium smoking was prohibited by law in England itself) was pact of the accepted creed of Europe’s relations with Asia. So late as 1870 the President of the Hong Kong Chamber of Commerce declared: ‘China can in no sense be considered a country entitled to all the same rights and privileges as civilized nations which are bound by international law.’ Till the end of European domination the fact that rights existed for Asians against Europeans was conceded only with considerable mental reservation. In countries under direct British occupation, like India, Burma and Ceylon, there were equal rights established by law, but that as against Europeans the law was not enforced very rigorously was known and recognized. In China, under extra‑territorial jurisdiction, Europeans were protected against the operation of Chinese laws. In fact, except in Japan this doctrine of different rights persisted to the very end and was a prime cause of Europe’s ultimate failure in Asia."
