Overview
- On Friday former Japanese minister Hideki Makihara published a social media post blaming Indian negotiators for delays and saying Japan had been sidelined on signalling and rolling stock.
- India's Ministry of External Affairs responded the same day, calling the remarks an individual opinion that is at considerable variance with the facts and saying talks with Japan are proceeding well.
- The dispute centers on signalling and train procurement: Japanese commentators say India moved toward the European ETCS-Level 2 system, while India says the signalling ordered meets international specifications and that no Japanese offer was received.
- Indian officials report recent civil‑works milestones and confirm a phased opening plan with the Surat–Bilimora section targeted for August 15, 2027 and Japan's next‑generation E10 Shinkansen trains expected only in the early 2030s.
- The row highlights wider stakes for India–Japan cooperation because procurement choices shape long‑term supplier ties, domestic train manufacturing plans and political narratives that could affect future bilateral talks.
