China Southern Airlines has resumed daily flights between Delhi and Guangzhou, restoring a key air link suspended for years. The service restarted on September 21, 2026. It is the latest sign of improving ties between India and China. Direct flights were halted during the pandemic and stayed suspended amid border tensions. Their return makes travel easier for businesspeople, students and tourists. Trade between the two countries has continued to grow despite political strains. China is one of India’s largest trading partners. The daily service is expected to boost cargo as well as passenger traffic. Airlines on both sides are adding capacity on India-China routes. More routes may follow if demand stays strong. Travel and business groups in both countries welcomed the resumption. It marks a practical step toward normalising links. Travel agents report strong early bookings, and more airlines are expected to restart suspended routes soon. Officials on both sides called it a positive step.
