One reason why Japan hesitated to export its high-speed rail technology was revealed by JR Tokai Chairman Takayuki Kasai, who wanted to make its provision conditional upon the “country being politically stable and governed by the rule of law.” He regularly highlighted the importance of compliance with enforceable contracts that would guarantee intellectual property rights.
而日本之所以在出口高速铁路技术方面犹豫不决，正如日本东海旅客铁道株式会社（JR Tokai）社长山田佳臣所说，是因为出口必须符合“技术受让国政治稳定且实行法治”的前提条件。此外他还经常强调签订的合约必须有约束力，能切实保护相关知识产权。
