The Delhi Metro system has been publicly recognized by Lt-Governor Taranjit Sandhu as a primary example of the collaborative relationship between India and Japan. During recent remarks, Sandhu emphasized the project's role in modernizing urban mobility, stating that the network has fundamentally changed how residents navigate the city.

The Delhi Metro, which began operations in the early 2000s, was developed with significant financial and technical assistance from the Japan International Cooperation Agency (JICA). It remains one of the most prominent infrastructure projects in India, often cited by officials as a benchmark for successful international cooperation. While the project is widely viewed as a success in urban planning, discussions regarding its expansion and the ongoing maintenance of its partnership model continue to be a point of interest for policymakers in both nations. Sandhu’s comments serve to reinforce the diplomatic and economic ties that have supported the metro's growth over the past two decades, positioning the transit system not just as a utility, but as a diplomatic achievement.
