Of the JR companies, JR East has been active for acquiring orders, but Yoshiyuki KASAI, chairman of JR Tokai that offered technologies to Republic of China, made an announcement of declining to receive orders due to the liabilities that could be incurred when trouble occurs in the People's Republic of China, where laws concerned have not been established fully, and due to the apprehension of outflows of technologies.
なおJR各社では、JR東日本が受注に積極的なのに対し、中華民国への技術供与を行ったJR東海の葛西敬之会長は、法整備が不十分な中華人民共和国においてトラブルが発生した場合の責任問題や技術流出の危惧から反対の意見を表明している。
