6. 让内陆和过境发展中国家参与的区域合作和一体化可成为一项资产 用以汇集有限的资源 取得必要的规模经济 区域合作的倡议种类繁多 诸如南欧东欧的促进贸易和运输项目 以及在南部非洲已生根发展的 发展走廊和分布发展倡议 分布发展倡议更是把一般的运输 特别是过境运输放在更广阔的社会经济范畴内考虑 从全面的角度看待运输问题 它认识到运输同其他部门的相互依靠性 例如 没有适当的运输系统就不可能有旅游业与农业或矿业的好景反之 过境系统可服务其他经济部门的需要 而其持续发展要依赖其他经济部门的不断需求 因此 必须采取更加协调的方式 以各种广泛的活动与方案 包括运输基础设施和有关的项目 来吸引投资
6. Regional cooperation and integration involving landlocked and transit developing countries can be an asset through pooling limited resources and achieving needed economies of scale. There are a variety of regional cooperation initiatives, such as the trade and transport facilitation project in South-East Europe and the Development Corridor and Spatial Development Initiative (SDIs), which has taken root in Southern Africa. SDIs place transport in general and transit transport in particular in a broader socio-economic context that views transport, from a holistic perspective. It recognizes the interdependence of transport with other sectors. For example, tourism and agriculture or mining cannot flourish without an adequate transport system and in turn, a transit system is there to serve needs of other economic sectors and its sustainability depends on demands derived from other economic sectors. Hence there is need to attract investment, in a more coordinated manner, across a wide range of activities and programmes including transport infrastructure and related projects.
