The war in Ukraine will be an important part of the discussions at the G20 foreign ministers' meeting, but host country India is confident that the economic problems created by the war will receive equal attention, Indian Foreign Secretary Mohan Kwatra has said.

"Yes, given the nature and the developing situation in the Russia-Ukraine conflict, it will be an important point of discussion," Kwatra told reporters on Wednesday when the foreign ministers arrived in New Delhi for a meeting.

"Questions relating to food, energy and fertiliser security, the impact that the conflict has on these economic challenges that we face,' among others, would also receive 'due focus," Kwatra said.

The meeting will be attended by 40 delegations, including Russian Foreign Minister Sergei Lavrov, U.S. Secretary of State Antony Blinken and Chinese Foreign Minister Qin Gang.

Following a welcome dinner later on Wednesday, discussions will take place on Thursday.

The G20 includes the G7 countries, as well as China, India, Brazil, Australia and Saudi Arabia, among other countries.
