3. 如果所设想的公约要扩大范围以涵盖海上运输以外的运输，便有必要明确限定适用范围，以便该公约不适用于绝大部分运输段不在海上的情形。此种限定将从实际意义上根本解决各公约之间的冲突这一争议颇多的问题，事实上，也符合贸易法委员会各项公约中最为成功的 1980 年《联合国国际货物销售合同公约》所采用的办法，即在货物和服务同属一项合同而服务占绝大部分的情形下，限制公约的适用（第 3(2)条）。若设想的公约在特别需要的情况下不使用这种办法，贸易法委员会将因未使用迄今为止最为成功的公约所使用的限制手段而受到批评。
3. With any expansion of the contemplated convention to cover more than the carriage by sea, it is necessary to clearly delimit the applicability, so that the contemplated convention does not apply when the preponderant part of the carriage is non-maritime. Such delimitation would, for all practical purposes, solve the much-debated issue of conflict of conventions and, indeed, conform with the methodology used in the most successful of the UNCITRAL conventions, namely the 1980 Convention on Contracts for the International Sale of Goods, which delimits the applicability of the convention when goods and services are included in the same contract (Art.3(2)) and services constitute the preponderant part. A failure to use such methodology for the contemplated convention, where it is particularly required, would expose UNCITRAL to criticism for not having used the same delimitation technique as it has used in its most successful convention to date.
