What we have already said applies to the relations between civilised countries. But the relations between civilised countries on the one hand, and uncivilised or semi-civilised countries on the other hand, are very much more difficult in many ways. Difficulties especially arise with regard to commerce. Many of the less-developed countries of the world, such as some South American countries and China, cannot, like their richer neighbours, undertake the development of their own resources. They lack money, scientific training, business ability, and so on. They therefore give what are called "concessions" to foreign companies or capitalists; that is, the Government of the country leases some industry for a term of years to the foreign company. The Mexican Government, for instance, has leased its oil-wells to English, American, and Dutch companies, and the Chinese Government has largely confided the construction and management of its railroads to English, French, and German companies. Now, in many countries where this happens, the Government is not strong enough or permanent enough to guarantee proper security of tenure to the foreign company to which it grants a concession; very likely some official is bribed to grant the concession to one company and then bribed by another company to cancel it, or the Government is overthrown by a revolution and its successor cancels the concessions it has granted. By this means, British workmen may be thrown out of work and their employment may pass to workmen in the United States or Germany. Consequently, foreign Governments--the Governments of civilised countries--gradually begin to intervene and give protection to their subjects who have concessions in such countries, provided that they have obtained their concessions in a respectable and proper manner. Competition between the different foreign companies then grows up; their Governments gradually begin to support them against each other in this competition, until at last it becomes necessary for the different Governments, if bad feeling is to be avoided, to try to arrive at some arrangement among themselves, fixing the way in which the concessions granted by this or that semi-civilised country shall be distributed among the subjects of the Great Powers. Something like this has been recently happening in China.
