On October 2, 2025, India and China announced the resumption of direct air connectivity between the two countries after a five-year suspension, in a major sign of normalisation of bilateral relations. Direct flights between the two countries were suspended in 2020 during the COVID-19 pandemic and were not resumed due to prolonged border tensions following the 2020 Galwan Valley clashes. India's embassy in China announced on its WeChat social media channel that flights between designated cities would resume by late October, subject to commercial carriers' decisions.

IndiGo became the first carrier to announce a specific route, revealing plans to resume flights from Kolkata to Guangzhou beginning October 26, 2025. The announcement followed Indian Prime Minister Narendra Modi's visit to China — his first in seven years — which set the diplomatic groundwork for improved ties. Air India was also expected to relaunch its Delhi–Shanghai route by year-end. The move is expected to significantly boost bilateral trade, tourism, and people-to-people contact between the world's two most populous nations.
