India and China resumed direct flights on Sunday after a five-year suspension, a move important both for trade and a symbolic step as Asia's giants cautiously rebuild relations.

Data from tracking website Flightradar24 showed the flight, operated by India's largest commercial airline IndiGo, took off from Kolkata's Subhash Chandra Bose International Airport in eastern India at 10:00 pm (1630 GMT) for Guangzhou in China.

The neighbours -- the world's two most populous nations -- remain strategic rivals competing for regional influence, but ties have eased gradually since a deadly Himalayan border clash in 2020.

India's government said the resumption of flights will boost "people-to-people contact" and aid the "gradual normalisation of bilateral exchanges".
