South Korean President Yoon Suk Yeol arrived in New Delhi on Friday to attend a summit of the Group of 20 major economies.

During his three-day stay, Yoon will attend three sessions of the G20 summit, hold a bilateral meeting with Indian Prime Minister Narendra Modi and visit the Raj Ghat memorial dedicated to the Indian anti-colonial nationalist Mahatma Gandhi with other world leaders.

Yoon is expected to use the G20 gathering to call for a firm and united international response to North Korea's nuclear and missile threats.

The meeting with Modi will focus on ways to strengthen solidarity in the Indo-Pacific region and boost cooperation in the defense and high-tech industries.
