India and China resumed direct commercial flights from October 26, 2025, ending a five-year suspension that began during the COVID-19 pandemic and was prolonged by Galwan Valley border tensions. IndiGo (flight 6E 1703) became the first airline to operate the revived service, launching a daily non-stop Kolkata–Guangzhou route using Airbus A320neo aircraft. China Eastern Airlines resumed Shanghai–New Delhi services on November 9, 2025, and IndiGo launched Delhi–Guangzhou flights from November 10, 2025. Air India announced Delhi–Shanghai non-stop flights effective February 1, 2026. The resumption follows the Modi–Xi summit at Kazan (October 2024) that normalised border patrolling arrangements, signalling a broader diplomatic thaw between the two Asian giants.
