序 从根本上说,提高各国之间的经济关系旨在提高有关各国社会成员的福利。至于能在多大程度上实现上述目的,则取决于以下几个因素,即各个国家的经济状况、政治形势与社会情况。然而,在每个国家里,这三个决定因素却经常处在变化与发展中。这种变化或发展则要求该国政府采取一些相应的措施。 Fundamentally speaking, improving economic relations among countries aims to raise the welfare of the members of the society concerned. The extent to which these goals can be achieved depends on several factors, namely, the economic situation, the political situation and the social conditions in each country. However, in each country, the three determinants are often in the process of change and development. This change or development requires the government to take some corresponding measures.
